MTN ZTE Switch X1-complaint

I'm complaining about handset purchased I made at Jabulani mall Pep stores.-MTN ZTE Switch X1<br> <br> I bought the phone on the 1st October 2014 charged it as instructed after doing so the phone started freezing, on the 2nd of October I returned it back, was assisted by Ouper who technically fixed it himself, and said I should stop using the phones pattern security system, which I don't understand why because its part of the phones features, he then gave it back to me.<br> <br> 2 weeks later I came across the same problem took it back and it was taken for repairs and came back after 3 months, I was told I would be contacted once the phone came back but I was not informed the phone had returned I was the 1 who had to keep following up with them, after I had left an alternative number where I can be contacted.<br> <br> It then came back and worked for a week and it's still freezing, I took it back, this is after 3 months when I took it back the consultant said this barcode is not matching the handset meaning we had been given a new phone and not notified, but however the phone is NOT WORKING, and this 1 is even worse the camera is not working I don't <br> <br> I'm very disappointed with this service this
