No response to account queries

Since March I have been receiving incorrect accounts from MTN. I have logged two queries through MTN Active, the first of which says 'Closed' but I have had no communication and nothing was resolved. The second is still 'Open' since April. I went into a branch and no one could assist me and another request was logged on the system. I have tried on a number of occasions to contact the call centre but no one responds even after holding on for 30-45 minutes. I recently sent two emails to customer care and again I have had no response. <br> <br> I am now hoping that this complaint on this website will get someone to respond to me and to deal with my questions. My final option is to send my complaints to the ombudsman and hope they can get a response.
