I was given an Anytime 100 instead of Top up 200

My upgrade selection is Top up 200 contract as per old contract, which would charge me R670.00 per month. End of July 2015, I was Debited R2231.15. I reversed this transaction. Went to MTN Sandton City for assistance and clarity on what contract I am on. The Gentleman told me it was Anytime 100. I told him that it is not what I wanted. He told me that there was nothing he could do. I requested the documents I signed and proceeded to inform my lawyer. I received an email with a 1 page document not specifying which option I had selected. End of August, I was then debited R9178.12. I reversed this transaction again. I went to MTN Rivonia road. Spoke to a lady called Lerato. She advised that she could not assist however put a limit on the contract for R200. Then I went to MTN Sandton City. Spoke to a gentleman called Paul. He advised that I am liable for the R9189.52. He filled in a form which he said he would give to the lady who assisted me with the upgrade and she would call me. There has been no call from her, only an SMS today advising me that my services have been suspended. THIS IS APPALLING SERVICE AND I WANT OUT OF THIS CONTRACT. PORT MY NUMBER BACK TO VODACOM AND LET ME BE!!!
