I sent 3 mobiles in, got paid for 1. The other 2 have pass codes on them, I knew one which I sent back on the request email. I do not know the other which again I sent back on the request email. But since then have heard nothing. So if you are not going to pay me for the mobiles, then send them back!!!!
Very bad experience with this company. They gave me a quote for $100+ each on 2 old phones (Samsung S9+ 64 GB and Samsung S9 256 GB) and I sent the phones which were in good working condition. They came back with some standard response citing display issues and offered $5 instead for each phone or they could send it back. In hindsight I could have given those devices to someone who needed it.
After my devices being received over 9 days ago and my order being processed, I am still waiting on any payment. I emailed 3 times with no reply, until I advised I was taking it to the ombudsman, and even then I got a stock standard reply. My husband was going to send in 2 phones a tablet and watch and now he will not. I work in management of a customer service company and I would have to say this is some of the worst service I have ever received .

The hostility and abuse that came from staff when questioning why they were happy to give me an offer then decide last minute when they have possession of my phone that they wanted to knock off over $400 in price, I not once said the phone was brand new. I was told im stupid and told to shut up. I become reactive in fairness due to being treated poorly as anyone does, to then be stopped by a hostile male who has no customer service skills and told f you on the phone when I said their surface was dodgy. I have put a report in with the accc and am still waiting correspondence from this mobile monster company and I am also still waiting for my $800 phone to be returned back to me in the condition it arrived to your company in.
Sent my iPhone express, absolutely no issues with device. The phone was bubble wrapped and in protective envelope. Package arrived and they lowered their price by $290 as they said the screen was cracked. When asked for prove of damage they took another day before emailing me a picture of a filthy phone with cracks and chips missing. Nothing like the quality of the device sent in. Emailed asking why is was filthy with finger prints if it arrived like that, and why the price was lowered so much. Mobile monster again taking over a day to respond.
I am leaving a one-star review for this experience. This is regarding sell order number 235402. I sent in my device, and Mobile Monster claimed it was not in good condition due to a black spot. However, I am certain that there was no such issue when I sent it. Despite this, I requested the device to be returned. I then took it to Samsung, where they repaired it, and it was restored to brand-new condition. After that, I dropped off the phone again at Mobile Monster. This time, without informing me, they approved the device for $600, significantly lower than the original offer of $860. Throughout this process, they have been extremely unprofessional. They make customers wait forever for payment, yet when it comes to their own deadlines, they are suddenly very strict. I strongly suspect that the phone was damaged while in their possession. I reached out to them for a resolution, but Blaine from their customer service team was extremely rude, dismissive, and unwilling to help. He even said, "You can do whatever you want; we will not do anything." When I asked them to return the device, he casually mentioned that they would send it back and provide a tracking number after a week—another unnecessary delay. After being a loyal customer for three years, this is how they treat returning customers. I have tolerated their slow process—waiting five days for assessment and another five days for payment—but this time, they crossed the line by trying to cheat me. I am seriously considering raising this issue with ACL (Australian Consumer Law) for investigation.
Waiting over 2 weeks now for the payment to come through for a phone I sent in. Have been following up daily and received radio silence. Phone calls to the listed go unanswered. Absolute scam Edit: Order M-242928-1. Miraculously got a phone call after posting this. Was promised payment end of day today (Friday 14). It is now 5pm still nothing. Recommend everyone to avoid this dodgy outfit. Will be reporting to the relevant authorities
