Poor service

I ordered few items which I want to cancel. I phoned the Customer service division and waited for about 10 minutes because the call waiting queue is always long at groupon. I purchased the items via credit card and requested for it to be cancelled, and asked for a refund. Although I paid via credit card the consultant told me that I have not made payment. This was very frustrating because I wait very long in the queue and I could not get assistance. <br> I will have to phone tomorrow again and wait a very long time in the queue for assistance. It is extremely difficult to cancel an order from groupon and you wait for ever. <br> <br> The is terrible service.
