I called and purchased a colling unit for my travel trailer, they requested a check for amount of sale. this was on 10-28-17, at that time I was told it would take a week to ten days for shipping. It is now 11-25-17 it the unit has not arrived. I have call a number of times and get their answering machine. I have received call back from their service and was told they would leave a message for a return call. I have received these calls but there was no information left with them. I have sent email's requesting information and have had not response. At this point I just want the product or my money back ASAP.
