GrOUPON dismal fail

I ordered a floodlight under groupon code ***F3F on 14 April 2015. After having posted on Hellopeter that they did not deliver, they promised to refund my money.<br> <br> So these people got into contact with me and apparently made a full refund into my account 0n 03 June 2015. Today is the 16th of June 2015, and still no refund. Now they aver that the fault might be with my bank (FNB Private Bank), and I must now supply them with my banking statements to prove that I did not receive the refund. NO, It does not work the other way around where they can simply provide me with proof that they have paid - I have to prove I did not get the refund - how stupid is that???<br> <br> Please people - don't do business with Groupon - they are not above board !!!!<br>
