Outraging service

I am contracted to MTN and took in LG GFlex phone to the Vaal Mall branch on the 18th of September (the navigation panel on the bottom left of the screen was problematic with touch sensitivity as I had to tap it a lot of times to work. They told me I'd get it back in two weeks, still waiting, they do not bother to send me updates or nothing, went to the branch again last week Thursday and was told that I would get my phone in three days, still waiting.<br> The service there is horrible, the staff is not attentive to details (e.g upon applying for my contract I supp**** my ID, proof of address and filled in docs and my name on my statement and notifications is still spelt incorrectly) and quite frankly they do not give a damn about their customers. MTN is the worst decision I have made and I regret ever making contact with them - I do not advise anyone to take a contract with them or have any sorts of affiliation to them (ask around, do not take my word for it if you doubt me). I am currently paying for a phone and service that I do not use/ is of no use to me. I WANT MY PHONE BACK and want some decency to be practiced by yal nxa.
