Six weeks and still waiting for screen repair on P10 light

Huawei Canal Walk have had my P10 light for a screen repair for six weeks (booked in on 21 November - today 2 January). Still no word from them. I have tried emailing and phoning the shop and the call centre on numerous occasions and still no joy. The shop doesn't respond to email or phone. The call centre keeps telling me they will get back to me with progress and they never do. Help! What should I do?
