My account under international ***** investigation

Good day,<br> <br> On 25 Feb 2015 I bought an item on groupon, they deducted money from my account and I received a invoice from them confirming my order. A few days later I tried to access my account and the website stated my password is wrong, after resetting my password the website still would not let me access my account. I phoned groupon and asked what is going on, they said my account is blocked because it is under international ***** investigation and that I should wait and that somebody from their side would contact me. I waited a few days and nobody contacted me. I contacted them again and stated my problem, and I only received a email stating that I am under investigation. I phoned them again recently where they again said that someone from their side would contact me immediately, I am still waiting to be contacted.. I have not received my order which should have been delivered within 14 days of purchase. They took my money and never delivered. I did not have this problem with other items that I bought from them. This is bad service from their side, they have made no effort in resolving this problem. <br> <br> Please help
