This is my second interaction with Mobile Monster. As before, the service is as promised and excellent. I sold 3 Apple iPhones of varying ages. The prices were fair, the process efficient and the payment prompt. Mobile Monster communicated next steps along the way. I recommend them.
No one answers the phone. An email I sent went unanswered. Very poor communication. Sent an email today. Hopefully someone answers it. Will not be using this company in the future.

I highly recommend this business, their costumer service is second to none and is outstanding. I was completely impressed with their professionalism and customer service.
Beware of Mobile Monster's Unethical Practices – A Disappointing Experience
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
