Pathetic MTN Service

At the end of November 2018 I was debited twice the amount of what I normally pay. I call the famous 808 call centre and the lady tells me that yes MTN has had a "network issue" and this had happened to alot of customers. So to resolve this my number will be put to the list of customers who have been affected. I was promised to be call on the following Monday 3rd December when the billing department opens and I have had no feedback gone 3 days so far. So I called MTN again and they tell me my query is still being processed. Again I ask when should I receive feedback and what really ****ed me off was the consultant telling me to phone them again in 14 days to check if this matter was resolved. I cannot express how disgusted I am with MTN service. December has passed and again I was debited the same amount. This calls for legal matters now. Beware of MTN.
