R6000 deducted wrongly

I had two data accounts with MTN.<br> Last year December I had changed the one line into a normal mobile line and left the other one.<br> Early in the year (either Jan or Feb) i closed my one data account as i was not going to renew it and just received another deal at another service provider.<br> Months went by with no issues, in July i had just more than R8,000 deducted from my account, this was a two month deduction for both the data line I closed as well as the mobile line.<br> <br> Upon us investigating in July, the response from Tygervalley's branch (on our second visit due to no response) was that we (all of a sudden) had called in a week before to close the data line that was already suppose to be closed.<br> <br> This is quite weird as only after we complained, did we, supposedly, close the account by calling in? I've requested the recordings but no response yet for all interactions with MTN from the beginning of the year, but with no response.<br> The recordings will and could cover both parties and reveal the reality.
