Terrible call centre and store service

Traveling overseas and my billing limit was reached. This comes after I just renewed my contract and the person upgrading my contract took it upon herself to reduce my limit even though I said it needed to be open because I travel. NONE of the call centre numbers work and I tried them all!!!! Finally get someone from SA to call the MTN call centre and get them to call me. They do and when the call drops after a minute they NEVER call back. Convenient!! Shocking service on so many levels. I then call the store where I upgraded my contract and explain my situation. After all of this the lady asks me if I can come into the store that evening!!! Shocking service with a side of stupidity. MTN should review their customer service especially considering the amount charged for contracts. Clearly they don’t care if their call centre numbers don’t even work properly.
