Purchased a Huawei Ascend Mate mobile phone from CPW 3/2014 on a 24 month warranty. I put £130.00 up front. Within 4 weeks the phone had lost email and SMS notification tones. As I was in Scotland I went to CPW in St. Andrews. They couldn't help. To cut a long story, this has happened 4 times now and the only way to recover is a total factory re-set (lose everything). I allowed CPW to send the phone away for repair. Two weeks later it came back with the same fault. In July the notification tones went again. I took it back to the CPW store and asked for a replacement. The Manager said he wasn't authorised to do that and offered a £200.00 upgrade !!!! I asked who I should speak to. He informed me that I should speak to the CEO and gave me his name and CPW's head office address in London. Despite 2 recorded delivery (and signed for) letters CPW remain silent. I emailed their on-line complaints. They have sent me 2 emails saying they have never received any letters from me. I have proof of posting and proof of signature by CPW. I have tried to be reasonable but it looks like I'm going to have to invest some money and take them to County Court. Has anybody else had the 'silent routine'? Philby
