Terrible services

<p>I had initially cancelled one of my contracts on the 4th February 2017. Vodacom still proceed to debit me at the end of March. When I called in, I spoke to a lady and she said yes I did call in on the 4th and Vodacom didn't process it.. After calling the whole day I finally cancelled the contract and app**** for a re fund. I called in this week to find out when I'm going to be refunded. They said they have no record that I called in on the 4th and that too them I only cancelled it on the 28th of March. And they won't refund me. I asked for an itemised billing to prove that I called them on the 4th and didn't sende it up till now. However I have it under my call log that I did call them and was on the fone for 13min. I just want my refund</p>
