I orderd a pair of plastic fenders over the phone from Lenden the service maneger. The info he asked for was the vin # of my RV. He said the only other info he needed was a color, dark or light. When the fenders arrived I imeadeatly noticed the screw holes were different but he insisted it would fit. Less than an hour later I called him and told him everything was a mismatch, nothing fit or lined up. He then informed me there was no returns or exchanges. I tried to explain that either keystone or family rv should make the perchase right. After getting nowhere with Lenden I tried to talk to someone else in person. That person was Jerry Baird, the owner. | Jerry informed me that Lenden was his son and he was being kind by tring to half the cost of the new fender reorder. I told him that I already paid for the fenders in full and it was their responsibility as authorized keystone parts dealer to provide the correct part. | I provided the RV vin # and recieved the wrong part. Jerry quickly got adgitated and said there is no offer to help. He used profanity and told me to get off his properity. When I didnt move fast enough for him and tried to tell him his companies customer service was terrible, he violently threw me to the ground. I sufferd a skined up arm and was extreamly shocked and humiliated. | I called the Pomona Police and told them I was just assaulted and please send an officer. I told them what had happend and they then went in to talk to Jerry. Unfortunately Jerry had left the rv lot quickly. Odd after only arriving about 20 min before. The officers told there was no security camera to review (unfortunately). And the only people to see what happend were his employees. | They lied for him and said that I was aggresive towards him and he acted in selfdefence. Im 5’7″ and 155lbs Jerry is around 6′ to 6’2 and about 250lbs. I dont think violence would make much sence here. I have read other reports of him acting violent to his customers. I think this is a serious issue and its just a matter of time before he hurts someone. | The police said with no wittnesses to my side of the incedent they couldnt do anything. I think its sad that a business owner with multiple accounts from customers of violent behavior can continue to do business.
