Terrible service and bad workmaship

I took my HP laptop in for repair as instructed by HP to use LMR. the laptop went in at the end of 2014 as it was constantly shutting down. It took over 3 months to repair and I had to constantly request updates. I paid the repair fee and took the laptop home. The problem had not been fixed and after repeated attempts to speak to the right person I took it in for repair again. This time it took 5 months to repair and I literally lost count on how many emails I had to send. I was told multiple parts had to be replaced and even went to their branch in Kyalami when they said it was ready. I arrived and no surprise they couldn't find the laptop due to a move. I finally received the laptop back 5 months later and with in 2 weeks it failed again with the same problem. I had to travel overseas and could not return the device, I was also so annoyed I put it away. I have now requested they repair it again or refund me my money only to be told its out of their 3 month warranty so they will not do so. As a HP recommended repair center i have never seen such bad service and clear unskilled technitions. I have paid money only to have this service
