What is the name of your state? Wisconsin Hi, I was recently over billed for some hauling I subcontracted through my business. I verbally committed over the phone on a price and when sent the bill it was $400 higher than what was agreed. I paid the agreed upon amount in full. However, the other party is now threating me with collections unless the bill was paid in full. I am a sole proprietor and I did not receive or sign any documents agreeing to any price. What should I do?
