No follow through regarding previous complaint

I made a complaint on Hello Peter in December 2015 about my Acer laptop that had a main board that stopped working 10 days after the 1 year warranty was up. I received a response from a \no-reply"email saying my problem would be attended to. I received another email saying it was being dealt with on 22 December. That is the last I heard from Acer. I have no-one I can contact and I have received no further communication. What poor service! Perhaps Acer was hoping I would just go away and forget that my 1 year old laptop was a piece of garbage as I am not prepared to pay the R6800 to have the main board replaced. It is very clever of Acer to respond on a \""no-reply\"" email so their customers cannot follow up with them. I am so disappointed in Acer as I was sure that they were a reputable company"
