Over Charged

Couple of months ago, I changed my details and couldn't update any info with Telkom, however I went in errors for couple of months which when they called me beginning of the year and I made an arrangement of three months, the first month of the arrangement was fine, then the second month they debited the arranged amount then the following day an extra R731.41 was debited and when I called Telkom I was told they cant find any information/arrangement made however my account does show that I paid R379.79 which was the arrangement made with Nudebt which is their collection company, then later that month the lady from Nudebt called me to make the last arrangement then I explained to her what happened and she said she will follow up on my behalf as she also doesn't understand why Telkom would ask them to collect on their behalf and not have records, I since been waiting for her response, then end of April and extra R379.79 was still debited of my account which was also not authorised by me. now Telkom owes me and I've been sending emails to Nudebt and Telkom (Ntsako Mnisi and Millicent Ndiya) but none of them has had a decency of returning my emails.

Telkom also had asked me for my banking details where they can debit my monthly instalments, and I told the consultant will not give him my details as they are still the same as the once I gave to Nudebt and up until they sort out my account and refund what is due to me that's when I will update my details with them.
