Handed over, but pays every month

Nashua Mobile migrated the contract to Mtn last year Oct (2014). We struggled for 2 months to get details of bank account to pay cellphone contract, and have been doing so every month by EFt with ref no:N*** SR Erasmus, A few months ago my husband got a call that he is in arrears, where after we went to MTN with proof of payments for 6 months, they did not allocate it to the contract. On the 16 November, handed over to Shapiro Attorneys for an amount of R 4 588,98, we went to MTN, and they cannot access the account as it is with Legal, we cannot contact Legal either, we want an up to date statement. *** (Melissa) sent mail to Legal on 21/11, she will phone me back on 25/11. Did not get a call back, tried to phone her today, phone just rings. So I phone MTN Head Office ***, spoke to Eurika, (***)again cannot see anything as account is with Legal, she will mail them, 48 hours turnaround time. In the meantime, we cannot upgrade other contracts, due to bad credit record, and this by MTN's negligence and incompetence. This account is past the 2 year term, we want attorneys to be informed, corrected credit record, and to close this account in total.
