Over debited my bank account

I can confirm that I logged a complaint (case ***) with Telkom mobile billing department since 24.02.2016 and was promised a turnaround time of between 2 to 72 working hours, however to date no correspondence has been made with me. I made a follow-up this morning with their call centre and the lady I spoke to confirmed they do not have any direct contacts to the relevant personnel, she could however see that my query has not been concluded.<br> <br> What happened is I recently upgraded my contract and the agreement was that an amount of R199.00 will be debited per month, to my surprise I received a sms last week stating that R864.62 will be going-off my account on the 29.03.2016, which indeed happened. <br> <br> I am terribly disappointed with Telkom's deceit as I have been a loyal client to them for the past 2 years and for the first time ever I got to rate them 0 from the previous 10 out of 10's I used to give them. <br>
