Dion wired. Bad service with faulty dell laptop

I bought a Dell laptop from dion wired last year February and in December they said my warranty expired. I took it in because it was faulty and said the hard drive was not installed after 8 months of use. It took them over a month to sort out, which I paid the technicians fee for. After getting it back. It has the same problem as soon as I started the laptop. I have to continously follow up and receive slow response. I bought an expensive laptop that I can't use. So disappointed
