Debiting money from my account to make their target at call center

As a Telkom user I am very disappointed in them because I didn expect this from them. I took a wi-fi router with them which is r99 per month in November.first deduction was December.telkom deducted r570 out of my Capitec account just as they pleased. I went to go query it at a Telkom store at the waterfront. I logged a case which was told to me I had to wait 48hrs for them to respond,went back 48hrs later still no respond from them. I was totally ****ed and went the following day.i went there the consultant told me it has been resolved,however they are only willing to credit a r60 back into my account every month.for my own money.which was their error. I phoned the call center to speak to a manager. The manager couldn’t come to the phone because she was busy.Nokuthula was her name,I emailed her still no response.telkom is pathetic most junk network ever..please would not recommend Telkom to anyone.
