Poor Customer Service & Communication

I returned a product to Groupon on the 14th October 2015. On my status it has the product's status as \refunded"but I am still waiting for my refund (it is more than a month later). I have emailed numerous times with a mere \""we are experiencing high query volumes and can't get back to you\"" automated responses. I have tried calling this morning only to be told their systems are down and they are unable to help me \""at this time\"".<br> <br> On the 27th October (three weeks ago) I ordered and paid for a different product. This has not yet arrived and no feedback has been provided on the progress of delivery. Same story w.r.t email queries sent and this morning's phone call.<br> <br> Groupon seems to after all these years in business still not have found a way to communicate effectively with clients and/or employ enough staff to deal with queries around product purchases. I don't know whether it is due to poor management or poor planning/structuring inside the company but I am so annoyed and disappointed."""
