Poor service from MTN.. Account handed to attorney

Mtn handed my account to attorney after they failed to deduct the amount of R428 for a cellphone contract and suspended sim card without my knowledge… and first month wasnt aware that they didnt deduct, second month i noticed they didnt debit their money … On May 15th i Phoned Mtn call centre for follow up and we made payment arrangement, i did paid via EFT of R920 for Apríl and May

Payment were not allocated and updated by collection deparťment, Mid June i followed up was told that i didnt pay and my account is still owing and its already handed to attorney…i then sent an email to collection department all together with proof of payment but still not getting help…been calling Mtn and Attorneys they are not helping.

Its been a week now, sim is suspended.. my account is arrears and this is ruining my credit profile
