Groupon not paying suppliers

Hi Groupon,<br> <br> I paid for my cruise that was advertised at R11700.<br> <br> I receive an email now from MSC Cruises stating I am R580 short?<br> <br> If that is correct the advertised amount was false.<br> <br> In addition to this, the onus is on Groupon to provide proof surely as Groupon was the recipient of my money and its Groupon that then pays MSC.<br> <br> This is a very serious issue as it indicates *****.
