Groupon service is terrible

On the 27/11/2015 I purchased 6 bottles of wine (Groupon code: ***Q) - 4 bottles arrived. I notified Groupon of the short delivery, and they promised to reimburse me the money for the missing bottles.<br> <br> Initial cost = R149.50.<br> <br> After calling and speaking to various people, R30 was placed as a voucher on the website. I called again, and spoke to Ricky - who promised that I would be refunded the correct amount (R50) into my bank account. <br> <br> On checking my bank account - nothing. There is now a R45 credit voucher sitting on the website.<br> <br> The following action needs to happen:<br> <br> 1) Pass a credit for the correct amount<br> 2) Refund the money into my bank account<br> 3) A signed letter of apology to be provided for poor service by the CEO of Groupon<br>
