MTN ******, encouraging cyber crime

I am so disappointed in the service I received from MTN. I have a contract with them, which I have been paying religiously. A consultant from MTN decided to migrate my contract without my knowledge and consent, as a result my household has not been able to use data for over a week now. I called their call center and I was referred to the store. I went to the store and I was referred back to the castomer service online. I wrote an email to customer service and asked to be assisted, instead I received an email requesting personal information which I already provided in my complaint email.

I feel hard done by MTN, in a sense that they were able to access and make changes in my contract without my consent in the rife times of cyber crime. Secondary to that I am being sent from pillar to post in pursuit of rectifying the inconvenience they caused. How is that treating customers fairly? Had I not honored my obligation of paying premiums, they would have been quick to blacklist me. MTN is really very bad in customer service. I am really pained by them. Why should I suffer for their ********* behavior?
