MTN,s Pathetic Customer service

SMS roaming was activated before going on holiday and I have been attempting to deactivate it for 3 days, without success. In the interim I cannot make any calls or use mobile data, and this is restricting my personal and work activity.

I was told that the deactivation was escalated to a specific department, but they are closed on weekends, however it is now Monday, and I am still waiting for the deactivation. MTN does not care about their customers' mobility and safety. I have also received no feedback from MTN and have been calling their call centre daily to get "updates". MTN does not understand the concept of customer service.
