DID NOT CHOOSE CURRENT CONTRACT

My contract has expired and had a call from Fusi Kutoane in April to renew my contract with the same as I had (2gig) for R89.00 per month for 24 months. I asked him to send me an email with the details, which he did and I rep**** to him to proceed with the contract. This month (June) I receive an statement for 3 gig and a huge amount to be paid. I sent and email to Autopage, and they rep**** that they would have a look at my case (reference number 713695). I also said that they should correct the incorrect statement as well as the contract which I did not ask for. All that I received was a email from Autopage that the case has been closed. I did not ask for the 3 gig and am not going to pay for this.
