No availability for Groupon to Mauritius

Hi all. We had a very bad experience buying a Groupon voucher for a great Mauritius deal from Aloha Travel Agents. Enquiring for availability for our Groupon bought(only supposed to expire in June), there is NO availability!! But the deal is still being advertised and you must buy Groupon before you can enquire for availability. I tried for Feb, March and April and they said No, only in May. I then asked for May dates and just no correspondence from them now ?!! :(( but after my first enquiry they did offer me other deals on their books :(( which of course I am not interested in :(( Is this a way of getting clients to in on other offers?? After first enquiry and seeing that I am not interested in other deals, Audrey from Aloha suggested I ask Groupon for refund within 7 days! Bad experience which also puts Groupon in bad light :(( :(((( Be careful when buying holiday Groupons and stay clear of Aloha Travel :(((
