MTN Clearwater shop service is eMTNy

I handed in my faulty LG phone, still under warranty at the MTN Clearwater store in August for repairs. They told me about 10 days, 6 weeks later they send my phone back completely wreaked. So the whole process starts again another 2 weeks later, I'm informed Im getting a new phone, which was strange as only the volume button got stuck. Yesterday I picked up the replacement phone with a broken screen. So back to the shop and guess what, they need to send it away again. The customer service was terrible at best, if I didn't keep phoning they probably wouldn't have done anything. This is a business phone and due to not having a phone its been a huge loss for me. I have 5 lines with MTN and will not be renewing our business contracts with MTN.
