Bad service at Huawei Melrose Arch.

The service at Huawei Melrose arch is disgusting,My phone broke and i took it into Huawei Melrose to get fixed, they didn't fix it properly, the screen just switched off, i took it back in and they booked it in as a bounce on the 29 of November, and they have had it since. (their turn around time is 7-14 days ), I've been waiting for 53 days, with them telling me story after another, honestly now it feels like they dont know what to do, I've tried contacting them, going there in person and even resorted to contacting their facebook page, who **** to me and said that the engineers have received the part, when i call today to follow up, i get the story that they are still waiting for the part, and they asked me if ive received the invoice for the repair (The phone was in warranty when i took it in), Story after story after story i am experiencing with Huawei, honestly at this point i feel like reverting back to Samsung, they dont give you these issues. Honestly now, i am still awaiting feedback.
