Bad service

Worst "***kest" service and phone ever.Biggest regret of my life. Phone handed in on 22 August 2017 called the service centre on Monday 28 August 2017 and was told the phone is done and was sent back on 24 August 2017 then they were going to contact Canal Walk centre if the phone is there.Then i called again on 31 August to follow up on the call made the Monday the service centre agaent then told me the system reflects they waiting on a part which is supposed to arrive 1 September and assured me that the phone will be fixed by Monday 4 September when i called again the phone was not done and they still waiting on the part.Called again today 12 September still the same answers.Super infuriated.
