Billing issues

<p>I canceled my adsl and landline about a year ago due to service delivery issues.<br /><br />I had a credit amount in my account. In November telkom contacted me to return the credit amount to me. A few days before christmas I get a threatening sms from telkom claiming that I now owe them the amount that was refunded to me and I have 48 hours to comply else they will hand me over. When I contacted telkom they informed me that I had been double refunded, thus I owe them...<br /><br />I paid it, sent the proof of payment to them as instructed. A few days later I got debited the same amount. And now on the 10th I got debited yet again. So I have now paid my credit back 3 times???</p>
