Offer to purchase a house

I have signed an offer to purchase the house with the above company on the 1st Feb then on the 2nd Feb 2018 I sent them a letter of cancellation since I am going through a divorce and do not have money, they refuse to accept it they are forcing me to buy the house. People beware of this company. I have sent them a link from EAAB that says I have the right to cancel they say it does not apply to me.
