Shame on you Groupon!

In May 2015 I purchased 2 vouchers from groupon, 1 being a gift voucher. When the person arrived she was told that she needed a barcoded page from Groupon which I have not received. How embarrassing! I then contacted them the Monday and I was told that they were having payment problems. A few days later I eventually got through to the customer service team leader and was told to send proof of payment and they will refund me. I sent him the proof via email on 30 July 2015. Today, 17 August 2015, i asked for a follow up, which to his reply was \ Please advise what this is with regards to?"<br> This is really unacceptable! And to top it off they made it sound as if this was all my fault. I have not received any notifications from them with regards to any payment issues that they were having on their side. This is the second time I am having a problem with groupon. I had to wait a whole month before I received my refund. And now I await one again.<br> Shame on you groupon!"""
