entrapment to sign contract

I was told my repayment plan would be for 5 years. The contract which I was rushed to sign as I was told I had to sign on the same day, said the repayment would be for 7 years. I was ******** enough to sign as directed by the consultant rather than reading the content. When I finally received the email copy of the contract, I contacted their head office informing them that the financials were different to what I was informed about and I was not satisfied especially since I was promised other services by the consultant prior to signing, but none was fulfilled. I then requested the contract to be terminated as I hadn't utilised their services yet but I was told I cannot cancel the contract irrespective of the fact that they messed up with false promises and information. They will do and say anything to have you sign with no intention of fulfilling any of it. Stay away from these timeshare companies
