Service SUSPENDED again -lack of accounting skills

I refer to MTN's response to my previous complaint (REQ:***) on 30/03 at 11:52 - even though i paid TWICE this month against my better judgement, MTN has gone ahead and suspended my services yet again. I responded to their feedback advising that i want an explanation of how my account was reconciled as i was convinced that the suspension would reoccur and i was just proved right. It seems MTN will not answer me and they refuse to present me with a written reconcilliation of their accounting done on my account since December 2014. My account should now be in credit with R958.14. I do not understand why my service are being suspended continuously - i hereby request that i more skilled person is used to do a proper investigation into my complaint. If so required i suggest you make an appointment with me to sort this out in person. MTN certainly does not have a customer friendly approach when it comes to customer complaints OR even call centre assistance - please advise on management contact number so that i can have this sorted out - this type of NO SERVICE is hugely unprofessional and i am not sure why a company such as yourself thinks it's ok to get away with this.
