MTN incompetence

This is my 8th year with Mtn as a contract customer, I had 2 contracts with MTN, 1 for fone & 1 for sim & data. But the service l received from Mbali 1 of the consultants at their call centre was shocking, the lady is rude and arrogant, she deliberately misled me to call on a weekend when she knew that the cancellation department won't be working then, but since l was informed of their schedule, l had to insist that she puts me through to the cancellation department and what did she do, she had to frustrate me and put me on hold for over 15min. I eventually hung up the fone and upon redialing I was put through to the cancellation department in under 5 minutes. I asked for the reference number and this is the number for my conversation with MBALI ***. MTN is aware of my displeasure and they have since 12 October 2020 said we will investigate. Shame on MTN, I DON'T KNOW HOW THAT LADY WAS HIRED!
