I purchased a 4-bike carrier and discovered the main support tube is defective from factory (they didn't drill holes on one side, how am I supposed to insert the bolts to secure it?!) I've been trying their Customer service number all day long with no luck. Extended waiting periods, no one answers them beyond the main operator. Extremely poor customer service. I just wanted to get an exchange order going. Negative 5 start rating will remain until this is resolved!!!
