Query: Horrible Customer Service Experience

For the most part my wife and I are pleased with our high chair. The big exception has to do with the reclining option. Our chair has always had a problem with locking into a place. This presents a safety hazard if you think the chair is locked in the upright position and is not fully locked into place. My son, through normal movement, was able to jar the chair loose from the upright position and subsequently found himself in the fully reclined position. My wife tried to communicate with "Jeff" on numerous occasions with increasing frustration..."Jeff's" final communication was condescending and rude.I am glad to see others feeling our pain...even with the same customer service individual. Jeff's horrible customer service has motivated us to do whatever we can to spread the word. Hopefully, company reps will see their customer service person is hurting sales. For those looking for more contact information...They are in Ontario, California...not Canada.
