I made the mistake of borrowing money from a friend. She helped me with a personal loan and helped me buy a car. Through the 5 years this has been going on, there have been many many payments that I paid in cash and unfortunately did not get a receipt for because we were friends and at the time all was well. Since, the friendship has ended and she is making this loan more about personal issues than a business agreement. She harasses me verbally and continues to make this personal. I feel we are getting close to a payoff and have asked her 4 times to please give me a payoff balance. She never acknowledges my request, just ignores it. At this point it is her word against mine since neither of us has any real proof, such as receipts, and I feel the loan may already be paid off. Any recourse?
