Autovalue Hyundai Niagara Falls

We sold our car to AutoValue Hyunda after they called me to buy my 2016 Elantrai, actually the customer called the car coin toss. We were given a cheque from AutoValue Hyundai that we found out from our bank was fraudulent . Needless to say I was furious and went to the dealership and spoke with Matt the sales manager, who advised us they had known about the issue for 3 days. When I asked why they didn't call us to advise so they could rectify the situation he had no answer. We did get another cheque to replace the fraudulent one. I also advised Matt he should be compensating us for the 3 hours we lost dealing with the bank, it has been quite a while now and nothing has been done with compensating us. My daughter bought a car there a week later against my better judgement, they also advised her they will be compensating us. Well needless to say still nothing. We have purchased 3 cars here but will never purchase another vehicle at this location.
