Absolutely appalling service beyond belief. This is the FIRST and LAST time i'll ever use Carphone Warehouse. I've ordered an IPhone 12 sim free (£800), the money was accepted and received, the order was processed and due to be delivered. 2 Days after the expected delivery date i had not heard anything so i contacted them via online chat, to be told my order has been cancelled and i need to contact them to find out why... So i then email them with all my information, to then receive an email explaining they need my billing address to be able to help with my query (although my address was clearly stated), i then hadn't heard back so i decided to call them. I spoke to a very blunt member of staff (Ulanda) who wouldn't say anything more than "sorry you've failed an internal security check" and apparently no supervisors are available to help. I tried to get clarity as to what's happened as this is the first time using their service all i've done is gone onto their website, paid in full for a product, received confirmation that the order has been processed await for a dispatch notice, then not heard anything.. once again all she could tell me was i've failed an internal security check... 0 Customer Service, not even the slightest bit of understanding as to where i was coming from. I can not believe a company as big as this is able to exist, how and why would you completely refuse right of service to a first time customer who's paid in full via card...Utterly Shocking.
