Really badly manage company

Really badly manage company. They seem to have a really poor track over their inventory. I had issues with every other i have placed with this company. I call to my local branch to see if they have an item in stock they responded yes the system says there are x amount in stock, i ordered online for click and collect and they order took over a week to be ready for collection. The second order i placed, was also click and collect, for an item that was in stock at the branch, a few days later I received an email that the item was ready for collection. But wait hold on then i received another email ''sorry we don't have the item here is your money back''. their click and collect is a waste of time!!!

Disappointing Service

I ordered a product and it arrived 3 days later, however when opened it appeared to be a wrong product. I called Ballymount branch and a lady acknowledged that the wrong product was sent. She told me that someone will call me later that day. Nobody did, so I called them again and was told (no apology given) that the correct item will be send and I will get it the following day (Wednesday). I told them that I had a contractor booked for Friday. Today is Saturday and no item and I had to paid €100 to the Contractor who turned up on Friday to do a job but no items so no job and charged me 100euros for call out charge. Very disappointed with a service and delivery. Will not buy it or order from them ever again. Avoid, avoid !!!

Communication could be better.

Staff were very helpful unfortunately order was not complete and I had to chase for follow up delivery, 3 times I was given different delivery dates, all 1 way traffic until final driver Matt was in touch and arranged delivery as promised
