SA Homeloans

I am very upset with SA Homeloans as I feel I have been taken for a ride. I met with one of their agents while buying a place. She showed me her offer and informed me I'd get a further 1 percent off from the instalment. This is apparently a deal they have with SA government employees. I accepted and signed the offer. Only to get to the lawyers and be told nope, the 1 percent was already calculated into your instalment. I signed this offer based on what she told me and now I have to pay the lawyers wastage fees. I know I'm partly responsible but I do feel I was played. I cannot believe this is what people do to make money!! Lie!!! It is *********!
