***** case not handled well

I got a cell phone contract with Telkom last year in October for R149. When the debit order went off in December it was over a thousand rands.I called to find out what happened and I was told I have two contracts with them when I told them I knew nothing about it I was asked to sign an affidavit at the Police station and send it through. The affidavit was sent on the 19th of December and after 3 weeks of no feedback I was told to send the documents again. I emailed the documents on the 18th of January and till today there is no feedback. But Telkom deducts my account every month for all the devices that were taken despite the ***** case I had opened. I even had to close my account coz I get charged by my bank when there isn't enough funds in my account. When I asked them if I should pay for the contract that I know of I was told to wait till the investigation is done but that didn't stop them from debiting my account. Telkom isn't doing any proper checks when giving contracts as when I asked where these devices are delivered they told me they cannot trace those details. I need them to clear all these things from my name and refund me all the fees I was charged by the bank . I am disgusted by the service that I have received as when I call I get put on hold for a long time then my calls are dropped
