Groupon is horrible. They refuse to give my money back after a merchant’s false advertisement. It is TOO common that businesses do half the work or sometimes no work at all. Some aren’t even businesses; it’s apartment buildings, which is extremely dangerous. They let merchants get away with anything. They basically have the merchants policing themselves. They put customers in horrible situations to have their money stolen or worse. Customer service is a joke. They make it extremely difficult to get in contact with customer support and when you do they offered no solution, just half hearted responses.
