Awful customer service, ordered a phone in November but was wrong one so didn't even open sim just sent straight back with dpd! In January I noticed I was still being billed for this contract so contacted car phone warehouse straight away and asked them to cancel contract and refund money, they said they needed to investigate and it turns out dpd lost the phone but confirmed they had received it from me! Apparently dpd do not cover this refund under their insurance, so carphone warehouse are still trying to find a refund for me now another 2 months later! They also did not cancel the contract in January like I asked and I was billed again in February and again in March!! Have been calling over a month and the person dealing with it each time is conveniently 'not in work today' awaiting call back tomorrow!!
