Blackdown went into administration earlier this year after the owners' bank threatened foreclosure — but not before the owners called in Quinton Edwards to find a buyer.
Quinton Smith found Carnon Downs Garden Centre owner Mark Hassall as a buyer.
Solicitors were instructed, it was identified that the buyer had the money on deposit and due diligence was completed with completion due as quickly as the lawyers could manage. But in mid-June the bank called in Bristol-based administrator Baker Tilly.
Quinton Smith said: "I was called in because the bank was threatening to foreclose on the owners.
"I am a panel valuer for the bank on garden centres throughout the UK. I am a national specialist but the bank would not talk directly to me and although the administrators completed the purchase with the company that I introduced by the beginning of July, they won't pay my fees. This is the second time this has happened to me and I won't let it go without a fight.
"Having taken legal advice we are informed that if we had not found the buyer, the administrators or the bank would have had to appoint someone to do so who would have been paid fees and accordingly, they are taking undue advantage of the situation."
The bank did not comment due to "customer confidentiality". Baker Tilly also declined to comment.
