Harassment/Threatening/Bullying

We were recently told that the owners were selling a place we are renting. We had no problems letting people in & while we were there, with decent notice. We were then told the house had been sold & didn't hear from David until 6.30 this morning - phone calls & garden service knocking telling us the bank needed to do an evaluation @ 10am & that we needed to leave our keys, we refused. <br> <br> My Fiance left for work & I tried getting ready. Garden service then came to the door to tell me that he had been instructed not to leave until I had taken the call from David
