Century link Breach of contract Illinois Illinois

when setting up my contract I explained to this century link representative that I can only afford $75 a month. She assured me that my bill would be no more than $75. After receiving my first bill of more than $150, I called Century link customer service number. At which point the second representative told me that they would re-issue me a bill in the amount I was told to begin with. The next bill came it was more it was also more than $150. I called again. The third representative told me the best they could do was $130 a month. My question is who is in breach of contract? Needless to say I have not paid anything for their services. I feel that if a company tells you they will charge you only $75 a month then the bill should reflect only $75 a month. To promise that a service will cost one thing and then billing the customer a higher price is a rip off .
