Zero after sale service

I bought a Acer Aspire laptop from the Tyger Valley branch on the 25th of Nov 2014. I took it back to the shop after experiencing a problem. They referred me to Incredible Connection's service department to locate the problem. Once the problem was located, I took it back to Computer Mania after which they referred me back to Acer to sort out my problem. I've been advised to use Acer's online guarantee to do so. I've informed the person who assisted me that, I can't as my laptop does not respond, therefore I have no excess to the internet. The person was standing in front of a computer, but i was told to go to an internet cafe in order to get my problem sorted. This to me is extremely poor service as Computer Mania took the profit on the sale, but refuse to deliver the after sale service.
