No Delivery, Now returned goods Groupon :(

I ordered a product online. They said that it will be delivered within 14 days it's well over due. No one ever replies on their support emails only after sending a request online will they reply a couple days after. The phone number provided online never works (021..) finally I got a response from Groupon with my waybill no. I phoned the courier company they said that the product was returned. How could Groupon not pick that up? I track down a working number for Groupon online. The courier company apparently tried to deliver three times but we work from 7:30 until 5 there is always someone here, what happened? To top it off I phoned in when I placed the order to make sure they have the right address WITH MY CELL NUMBER if they get lost to please phone me. Now just to find out that once the product get returned I will no longer receive it. This is bull, highly disappointed with the service. Groupon will never see me again and not be supported by ME!
