Disappointing service from MTN

I am terribly dissatisfied with the manner in which MTN operates. MTN has decided to change their systems with no communication to their customers. From previously debiting in arrears they have no decided to debit the current portion, which led to me being debited double my normal payment without prior consent. When I queried this with an MTN agent i was informed that theres nothing i can do about this because it is out of her hands. There was no consideration of whether i would even be payable to afford this extra payment especially during this COVID- 19 lockdown and the fact that most of us are going without pay (No work= No pay). I am currently the bread winner in my family as my husband recently lost his job, and this month is going to be extremely difficult for us, because MTN has decided to take R1079 out of my account without prior consent.

I cannot cancel my contract with you because i still have 6 months before my contract comes to an end. Once that is over i am definitely switching service provider.

Lastly, i would like to appeal to MTN, to communicate their actions in advance to their other loyal customers before they decided just take what they feel entitled to.
