Thanks for your quick reply

Hi there. I am new to this so my apologies if there is another question like this. I tried to purchase an offer via Groupon last year (NOVEMBER). I clicked the buy now, entered my details and attempted to proceed however the screen kept returning to the "buy now" page. I contacted groupon several times and they advised that it must be my card (this was not the case as i contacted the bank) or credit issues?!!. After a few attempts i eventually gave up and ordered my product from another company instead! 3 weeks later my mum signs for a parcel at her address dispatched to me. After opening it i realised it was the product that i could not purchase. After looking on my groupon account, under the order screen it shows ((((Groupon no. 1 This voucher is not valid - your payment was refunded/refused)) This means i was not issued a groupon code to go to the sellers website and purchase the product. I received a generic email 1 week ago advising that they understand many people tried to purchase the item and due to a processing error the funds were not deducted. Then they ask that we either 1; kindly organise return 2. organise payment. Considering i was told the transaction was invalid and i was under the impression nothing was purchased what do i do now?! Do i have the right to keep the item under the "Unsolicited Goods Act" as part of the distance seller regulations?? Or do i organise return even though i attempted to highlight the fact that it wouldnt let me order it anyways! Any responses (that of a consumer law and not moral ) would be greatly appreciated.
