Query on Billing/Account

I had a prepaid account with Telkom where I had to pay every month and receive airtime. My telephone kept having technical problems due to cabling problems in our area. I attempted to close the account but couldn't get hold of Telkom, now I am receiving messages saying that I owe Telkom R1177.74 and my account has been forwarded to Nu Debt. This has been going on for the past 6 months and more. My concern is that how come I am owing Telkom this lump sum of money whereas I was on a prepaid contract and my telephone account wasn't active even worse I tried to terminate my services with them but did not get any help and now I cannot be owing them money on a line that is inactive. Its concerning because it has not happened to me only but I have a few people who experienced the same problem with Telkom. <br> <br> Your prompt response will be appreciated.<br> <br> Regards<br> Ms TP Masondo<br> <br>
