Horrible Service

I am writing to express my disappointment with the awful service I have been experiencing at MTN. Unfortunately, the level of service fell short of the standards I expect I had issues with my sim card where I was referred to Legal Team and was being provided with different amounts to re-connect my services. After jumping through the hoops to get that sorted I find that my sim card is not working and when I query I get told that I need to RICA my sim card. Fine I go RICA the sim card and 24 hours later my sim card is still not active. I query with the Twitter and I get told that my number does not need to be RICA but its on suspension. Suspension for what my contact ended in September I am now just paying for the data and insurance. I am being given the run around. Please can someone tell me what is going on. I am not sure if I still want to continue my contract after 13 years because of all this drama.
