No access for the past 4 months but regular payments were made.. struggling to get hold of a consultant to get my stuff sorted

I've been with MTN for our 8 years and open an business account last year where it has 3 additional accounts linked to it and since ive opened it I've experienced numerous problems.. the customer service is do bad .. my account has been suspended since last year December but regular payments was made on the account.. untill today im still trying to get hold of a consultant that i can speak to in order to sort out my account.. every time I call its just music playing in my ear for more than 15 mins then i drop the call an just try again . Ive made more than 10 calls on a daily basis i still haven't received a consultant for assistance. I need this matter to be sorted because I've been over spending due to the fact that o has to take alternative measure but monthly payments are being made . I need this sorted as a matter of urgency... you guys are useless when it comes to customer service
