Giftcloud

I received an email through Groupon in March to say if I took out a Motor Insurance through MoneySupermarket then I would be entitled to £50 vouchers through GiftCloud.com. I contacted Groupon after a month and was told that it was Moneysupermarket then MS said it was GiftCloud and not them. It took GiftCloud 6 months to investigate after sending all emails and evidence that I had back and forth and now they are saying they can't trace anything and I am not entitled to the £50 Gift card. It is disgraceful con and be aware!
