Telkom billing a mess

i have been trying to resolve this for 2 months now.<br> Telkom deducted R1196 from my account. turns out initially they said it was an error on their side. from when i cancelled a LTE contract as there was no longer coverage in my area - i could not use the item. they waived the penalty fee and my account reflects where this fee was reversed. i signed up for an ADSL line instead on the same day. now a year later they deduct this amount R1196 from my account again. initially it was confirmed they can see its their error now they say no its a penalty for cancellation. no one gets back to me this is ridiculous. and they can see the error but refuse to refund me. they also placed me on a debt collection agency database etc. but its their fault.
