Poor customer service

I rented a car with Dollar Thrifty in Or Airport even though the car was returned on the second day after the contract, those people have poor conduct in business and customer service always defensive before understanding the matter at hand and i mean from the manager to the lower level. Bad attitude and have no respect to clients all they look at is money coming in. I wonder who are the owners as they will loose many clients and maybe some can echo my statements who rented a car with them. Very poor service indeed and lack of professionalism on the telephone with clients. No one want to take responsibility and all speak the same mind without being objective and looking at the facts. I mean they had funds reserved and still went to debit my account and all of them refused to listen to me until i asked them to call the bank and then came back to find i was correct. The treatment you get is like you have ****** a car from them even though you consent to have past agreed date and do not mind paying. very stereo typed in thinking and their listening skills is poor cause had they listened properly they would have corrected this prior to my effort in calling bank.
