Very Upset client

I ordered me a tablet online from a black Friday sale. The item got delivered to my house within a week. <br> I opened the tablet and the power on button does not work at all. I still have the tablet a week later and yet they still collecting the tablet. I called the call centre and the lady advised me they will collect on the same day and nothing happened and no one contacted me. I even went to Facebook to complain on their site and they said we will sort you out. once again nobody contacted me or came to collect it. I think its very bad service from their side and especially from a company that sells very top class products. I would like them to give me a voucher for all this time and this tablet was for a gift for someone and their birthday is done and dusted. I could not give this tablet to the person due to Dion wired bad customer service and broken tablets. <br>
