Poor Service/ Bad attitude from front desk agent

i received bad attitude and poor service from the agent at Avis, Erie Airport today, the guy who was on duty at about 15h00 when we got there this sunday was rude, unable to assist proffessionally and had bad attitude towards us. the car we hired got broken on friday, we called road assistance number on the car keys, they sent a rescue team unfortunately they could not fix the problem. we then requested a tow truck to come pick the car, called avis again and the agent confirmed the tow truck will come tow the car and replace it. nothing happened on saterday. sunday morning we called avis, the agent confirmed the towing truck will come,eventually we went to avis at the airport to ask for assistance because the tow truck did not come. the agent there told us he wont say anything to us and wont assist us unless we have paper work and the car towed back. we politely told him we`ve been trying to contact the towing company we were reffered to without any luck and we called avis and were told they will come. we asked the agent to assist us by calling the number on avis car keys as well, he told us he wont do it without explaining nicely his reasons. he talked to us with disrespect.
