Over promised: Contract upgrade not matching sales discussion

After having my contract for a few months, a change to my contract was sold to me that promised improved services, but at no additional cost. I am now paying roughly R200 more than I wanted to. Please have a listen to my conversation with the sales agent, I was very clear about not wanting my monthly payment to change. I've sent an email to your customer care email last week, with no response to date. I would like things to be corrected ASAP as I cannot afford the higher monthly contractual amount.

Please contact me for additional information.
