GROUPON: *********** *******!!!

I purchased a hair salon voucher on 2 May 2015. Their OWN WEBSITE states: \no need to send us a proof of payment."On 5 May I sent a mail enquiring about my voucher as is still showed \""processing\"". I was treated to one of their automated emails. On 13 May I was treated to ANOTHER automated e-mail claiming that they will get back to me within 3-5 working days... 5 to 13 May ALREADY IS 3 - 5 working days DUMBASS!!<br> <br> Then I phoned them: \""No sorry ma'am if there is a problem with the payment you have to send us the proof of payment.\"" AND PRAY TELL HOW THE HELL WILL I KNOW THERE IS A PROBLEM???? \""They send you an automated email"
