second tablet not working after 6 day of use!!

I received my omega tablet a few days ago after having it inn repairs for more than two weeks. It worked for four days and since then it refuses to switch on. I have called the call centre on 5 March and spoke to a customer care team leader by the name of Chesnay and he advised they may not be able to give my money back because I purchased the device in November. <br> <br> I understand that but since I purchased it I have had endless problems and I don't think it's fair that I cannot get my money back.<br>
