Glocell/Autopage

I had a two year cellphone contract with Glocell, my monthly installment was about R189. I finished paying for my contract. Thereafter I received a notification that I was to pay R110 which seemed to be a monthly obligation. Later on I phoned them to ask what was that R110 I was paying for and I was told it was a continuing cellphone contract. I asked them to stop the contract because I had no knowledge or agreed to it. The consultant that I spoke to said she discontinued the contract. I want to state it clearly that after the two year contract I had finished paying. I never requested or consented to a new contract agreement and so I never even received a new phone.
