Bad service from Castle Gate MTN branch

I took my watch after one month back to theCastle Gate branch due to it being faulty. They kept phone for a day and advised that it was not faulty. I collected it and virtually it immediately had same fault. Took it back to branch on the Friday a week later they phone me to advise that they need the phone to do update first. After update watch was still faulty. It took the branch another week to send it to Samsung. When I followed up with branch I was advised if I want it faster i should take it myself to Samsung. Another week has passed and I have not heard from them. I Send anemail to MTN customer services last week Thursday and two follow up email there after to date I have not heard anything. No wonder branch is not concerned about their customer service.
