Incorrect debit order

I am having a huge problem with incorrect debit order. Bought data package from feature store for R118 a month. Telkom said wasn't available and sold me one for R126. Complained about the fact that it was still advertised. Telkom called said that the agent who spoke to me made a mistake and that I can still have the one for R118. So we changed it and went back to the original one that I wanted. Now they still taking off R126 even though that is not the one I have. I cannot get hold of anyone who can help me. I am not even rude to your agents just ask for a branch and someone who can actually help me over the phone, I mean its 2015 why must I go into store to fix something I bought online, she hangs up on me. You can go check the call it was at 9h00 on 15 May to my mobile. I was not rude your agents are unprofessional and rather hang up on clients than try and assist them!!! Can someone who can actually help please call me.
