Pathetic Service

On 17 February 2017 I bought 3 laptops from HiFi Corp Springfield, it was 2 Acer Laptops ( for my son and my Brother) and 1 Asus for myself. The Acer Laptops have never given me any problems I hardly use my Asus laptop in September 2017 I discovered that it did not want to charge I took it back to the store and it was sent for repairs, I collected it on 2 October, yesterday I discovered that it doesn't want to charge again, I challenge store to ask what do I do now as a customer. I was told by the service Department that I need to take the laptop myself to the technicians. I am very disgusted by the service i have received from the store I don't think I will ever recommend anyone to buy from the store. How many times should an item be sent for repairs for them to see that it's the manufacturers fault. I am frustrated if this is not dealt with accordingly i will have to contact the CPA.
