22 days later, and still no response

I bought an Acer Switch in November 2014. On the 3rd of March, it would not switch on, so I took it to Incredible Connection (where I bought it) on 4 March, and they said it would take 10 days to be repaired. I have been back 3 times, and while the guy at the service counter is friendly, I STILL have not received my Switch back, it is still not fixed, and I have not heard anything from Head Office saying that I can get my money back.<br> I am a student, and I need it for assignments, and for work.
