I live in AR. Although we have no signed contract we have hired someone to build a fence. They provided a diagram with optional types of fences to choose from along with the prices to do each type. We verbally agreed to a fence which was $3000. We paid the party $1500 down. I clearly marked under memo on the check 1/2 down (deposit) for fence work. The party signed and deposited the check. Now that the work is 98% done the party has informed us that he under estimated the materials needed to do the job and was going to bill us an additional $200 - $500! They are threatening to collect the $1500 and not complete the rest of the work if we don't pay these "additional" amounts. Obviously we aren't going to pay them a red cent until the job is completed to our satisification. Do they have a leg to stand on in trying to charge us more??? Thanks so much.
