Groupon customer service (There is none)

Over the last month, I have mailed and tried to call into Groupon call center on a number of occasions. <br> <br> Firstly with regards to the actually call center, I held for more than an hour on one occasion on my cell phone, and was unable to talk to an agent. <br> <br> I was trying to resolve a number of issues and as such then resorted to sending mails out to the support address. I have sent multiple mails and other than automated responses I have yet to receive a response from an agent. <br> <br> The service is ridiculous and the fact that there is no other means of contacting anyone at Groupon makes you want to deal with other site rather than them!
