Groupon took R4,999 from my account 2 months ago!!

Groupon took R4,999 out of my bank account for something that I never purchase and never received.<br> <br> Groupon IGNORE emails! Their Customer Call Centre is never operational when I try call. <br> <br> I have sent pleading emails, angry emails and desperate emails. I contacted my bank to investigate this. But this was 2 months ago. <br> <br> I am beyond furious and at a stage where I don't know what to do any more!<br> <br> Jonelle
