I bought a Groupon for Jiffy Lube location. That location will not service my car because my "car does not have a dip stick". Other Jiffy Lube locations within 25 miles will not take Groupon. Groupon always "escalating" my complain and request for refund. Groupon then denies refund due to past threes since purchase. Always tells me to transfer this Groupon to someone else. No one wants this Groupon! I will never use Groupon again.
