Unable to refund after they withdrawed Groupon listing

<p>On the 12th of May 2016 I bought a meal voucher on Groupon for Bertoua Restaurant in Durban. I received a call a couple of day's later from Groupon to say that the listing of the voucher was premature by them but they will sort it out. A couple of day's later I received an email with a Groupon voucher for the same amount because they could not get the restaurant to come on board. I requested a cash refund but nobody from Groupon is responding. If Groupon don't refund me I WILL take this furter and I WILL name the restaurant and Groupon must deal with it.</p>
