Telkom over-charged me

<p>I have been with Telkom for years and for the first time in April this year I was overcharged, i called them to enquire and I was told that they have enabled an out-of-bundle feature, the strange part was that every month I run out of data and this is never enabled, i told this to the consultant and he was not interested, he told me the only thing he can do for me is to disable the feature of which he did but I also told him to pay back the R500 I was over charged with but he could not help me, I therefore told him that I will be left with no choice but to reverse the debit order, of which I did. I called them again and I spoke to a very helpful lady, she changed my billing details back to normal, the only issue now was that the bank had blocked them from doing any further debits, meaning end of May they could not debit my account, when I came to this realization I called telkom to ask for their account details so I can pay the money directly into their account but they were never sent. I called them again today the 2nd of June to which I am told I have been penalised R500 for the failed debits. What I do not get is why I Am being punished for their mess up, one thing is clear I will not pay for something that is not of my doing. But I am willing to pay for the service I get from them which has of course been cut. Someone please help me.</p>
