Signed a contract for 2years

Dear Sir<br> <br> I am an autopage customer for nearly 3 years. In Dec 2014 I upgrade my contract and I signed another contract for 2 years for R341.16. Today I received my bill for June and I see that my bill went up with nearly R30.00. How is that possible? I phoned autopage customer care line and asked the lady how that is possible. She told me that the rates for vodacom went up, but that is unacceptable for me. Firstly: I signed a contract for R341.16 for 2years and secondly: I do have a separate contract from vodacom that is also a top up and that contract is and still is R399.00 p/m for two years.If altech autopage want to increase their fees then according to me, it's breach of contract. I will cancel my contract with immediate effect at no cost and we can go and fight this matter in the high court.<br> <br> your sincerely<br> Antheny ****s
