Overcharge large amount on my account, charged for 2 lines and long wait for refund

<p>I've given Telkom more than enough time regarding this. I even had my VA contact them directly numerous times to try sort out the refund.</p> <p> </p> <p>I moved into my home a year ago, a very old home - there were no phone lines, so Telkom installed one for me, only for internet purposes.</p> <p> </p> <p>I only realized late, that Telkom was charging me for TWO lines, one i have no idea where it came from. I went to the local branch, which said they'd refund me - That was over 8 months ago. </p> <p> </p> <p>After visiting the branch, and being insured that it was sorted, i noticed double debit orders going off again.</p> <p> </p> <p>The amount due for refund is around R3800. </p> <p> </p> <p>If there's any advice to get this sorted, please let me know.</p>
