Former Bradford chairman Gordon Gibb says he has a clear conscience over the situation that could close the Bantams.
Bradford's administrators have warned the club will fold unless landlord Gibb agrees to waive £300,000 rent.
Gibb told BBC Radio Leeds: "They have left negotiations until the 11th hour to put as much pressure as possible on me to accept a ridiculous request.
"I've been dealt with extremely badly and definitely won't be altering my decision making platform."
With Bradford facing a deadline of 1000 BST on Thursday, Gibb claimed he had tried to accommodate the club, and insisted their plight was not his fault.
Gibb said: "I gave them several options - one of which was to pay me when you have got it based on gate receipts, but that was turned down.
"The only people who have ploughed money in over the past two years into the club without taking anything out is the Gibb family.
"My conscience is clear. It's typical of the treatment I've had from Valley Parade over the past two and half years."
Bradford's Valley Parade ground is owned by Gibb's pension fund.
