Call listening

I have been calling mtn call centre to query my August billing and its still not sorted. In August my services got suspended and I got an sms saying I had reached my limit, surprised because I had never event spent 50% of that limit I called them. Spoke to Sindi Hansen who told me that from what she can see Im not even close to my limit she doesn't understand why Im disconnected and she reconnected me. When bill comes its double my credit limit and that was over a few days, I would never spend that much. Since then I have been calling and I still haven't been helped. September I called and I spoke to Themba Hamnca who said he has escalated my issue and the call with Sindi will be listened to because she gave me the wrong information. Come October still nothing. Called again and spoke to a few people who all told me the same, that they just spoke to their manager, call will be listened to and I will get feedback within 5 days..months later still nothing. In October, Mkhululi Botman even sent an email to Themba and Sindi and cc'd me asking them to assists, still nothing from them. Today I spoke to a very rude guy, Themba Mkhulili. The service is disgusting!!! I need this sorted asap
