Telkom Refusal to provide details of charge

I received a sms from Telkom VVM Attorney section regarding outstanding monies.<br> The account it relates to is a mobile contract which expired in October of 2013.<br> This contract was cancelled in 2013 and paid up- the reason for not continuing the contract was due to the fact that I was unemployed at the time.<br> I did inform Telkom of both situations -and due to the fact that my service was suspended- therefore I received no benefit of calls or data - I was under the impression that they would convey the information to their billing section.<br> Telkom have made no attempt to call my alternative mobile number -which they have - a Telkom prepaid number-or e mail me, which email address they also have.<br>
