No discount now not acceptable

I bought two stores some years ago and never used them due to issues moving and going overseas for a while I asked Anthony what i could do and they offered me a discount to take another store, I couldn't accept it at the time due to a guy who de*****ed me out of my funds but now when i can afford I get told that I can't get that discount anymore. Very unfair considering the amount i paid for the two original stores.
