SERVICE CONTINUOUSLY SUSPENDED

I had an account at Nasua Mobile and when they closed the contracts were passed on to MTN. I paid end of December and everything was OK. Then at the end of January I paid again and not long after, I started receiving messages to say that my account is overdue. According to MTN Nashua mobile sent through the incorrect contract. I was finally able to get the correct contract from Nashua Mobile which was subsequently sent through to MTN, yet I am still being billed incorrectly, which surprisingly changes every month.<br> <br> There are two contracts on this account. Initially we were billed incorrectly for only one of the contracts, but after a few months both contracts are being billed incorrectly. Another issue arose today when I was informed that my account is in arrears, despite having paid in full before the 28th of April. I received an SMS stating that the payment has been received and so am surprised to hear this. <br> <br> My phones have been suspended about 20+ times since the end of January. Before I was able to have the lines reinstated, but now am told that they will be suspended as my account is supposedly 30 days in arrears.
