Terrible Service and Pathetic customer service

I done a repair claim for my Samsun S7 Edge through MTN in october and was told to have it taken to WeFix Canal Walk. I dropped my phone at the store and had to have it checked. I was told that they did not have that parts at the store and had to order it From Samsung. I called numerous times and got the exact same message, they could not get an ETA. when I contacted the store this morning they said they are unable to give an ETA after 3 months. I was shocked as to how this could have not been resolved 3 months later! There is poor follow up from management, or very little interest. I have a holiday planned in thailand in Feb and will not have my phone repaired. I have been with MTN and using Samsung for than 5 years. This will surely be my last, pathetic!
