Hi there, I provided a written quote to a builder. They verbally rang and gave us the go ahead. I then emailed them saying thanks for accepting our quote, jobs booked in for June 17th, and attached an invoice for a 25% deposit. They paid the deposit. The job got bumped back and was meant to happen today. Yesterday, they called and said they've found someone cheaper to do the job so we had to give them their deposit back. I said no, and said I've purchased the materials already. They just called again and are threatening legal action because I don't have a signed acceptance form. Wouldn't them paying the deposit be a legal indicator that they have accepted our quote? Am I legally obligated to return their deposit under contract law? Thanks in advance for your answers.
