I have unfortunately only had problems with C.Warehouse. They occasionally sales call me to promote products & to upgrade & have consistently mis-sold me products. My latest upgrade seemed great, the deal was fine & I looked forward to receiving my new phone - at the store so I could get all of my details transferred from one phone to another. Sadly, the phone arrived at my home address which I'm never normally at but on the off chance happened to be when it arrived. The 'bundle' I'd agreed to buy was completely wrong - the phone case didn't fit my phone. They sorted this issue out after numerous calls. The sales advisor as a selling ploy told me I'd get £115 for my phone (which I told him had a cracked screen), but was told in store they'd only give me £65. I have spent a long time making phone calls to them & discovered that they've been debiting me £15 for about 4 years for insurance I'd cancelled years ago!!!! All in all, a terrible company who tell you that 'you should have done your research about how much a phone with a cracked screen would give you!' BAD CUSTOMER SERVICE. COMPLETELY INEPT STAFF WHO ARE RUDE & SPEAK OVER YOU! AVOID AT ALL COSTS.
