Hi, I sold my pony through a friend to a lady who had bought horses from my friend before. She paid a deposit and said would pay the balance owing the following week. She didn't pay. She then said that she needed to sell one of her horses to be able to pay the balance owing on mine. As she told this to my friend and not me, I didn't agree it and asked for payment ASAP. I have kept my pony's passport until full payment is received. The buyer then said for my friend to pay me as the buyer had bought another horse from her but hasn't yet collected it. Are these 2 separate 'contracts' because they are for 2 different horses and who should I be chasing the money from? I am extremely angry that I have no pony and no money!
