****s and Refunds

Hi, I purchased a Stainless steel Bad boy watch from Groupon in July 2015, it was After a few months of using it my husband noticed as soon as he puts the watch on, his wrist started to itch when we looked at the back of the watch it was green and corroded (which is not supposed to happen to stainless steel) I emailed Customer service & sent pictures to them. They picked up the watch in November 2015, I was told the refund will take at least 4 weeks and someone will contact me. No one has contacted me. I have emailed customer service several times and was told someone will contact me within 2 days, and again no one has contacted me till date. I sent another email last week and this time I got No Response at all. I JUST WANT MY MONEY BACK WHY IS IT SO HARD TO DO????
