Pathetic service from useless Huawei

Went in to Huawei store in Melrose Arch to have my device repaired and the technician named Justin assisted me and took my details to call mw back so that i could bring in my device to have it repaired as they had a backlog at the time. Till today 3 weeks later i am still waiting for Justin to call me back. I called the Huawei call centre 3 times already and still await a response from Huawei. This is the worst pathetic service ever received by a company like Huawei and clearly they dont value their clients that are using their brand.
