SUSPENDED 3G ACCOUNT, STILL BEING BILLED

Good Day<br> <br> MTN Statements: A***<br> <br> My 3G contract had expired as from the 25 April 2015. Firstly MTN continued to bill me as per the contract, instead of contacting me to have the account moved to 'Prepaid'. In April, we had issues with our WIFI at home and used the 3G for a short period of time. My account moved from R129.00 per month to an exorbitant billing of R6594.25. Regardless of the high billing costs, I paid R2600 on the account and have paid another amount of R1500.00. <br> MTN continues to bill me after the account has been suspended and I no longer use the 3G. They mentionded that my account has been handed over to their legal department for non payment??<br> I request to be refunded since the time the 3G has been suspended.
