Bad service

I purchased a laptop in Feb 20th and warantee was not explained. When I returned the item back with a faulty screen then they informed me the warantee does not cover the screen, they also explained that there will be a repair fee to be paid and that il wait a max of 21 days. I was happy with this outcome so far until when it came to that 21 days that they informed me about a quote. This is where I got upset as I thought ima pay the repair and collect the device. I then made numerous complaints which didnt help much, myself and my fiance went down to the store and show how upset and unhappy we were with the service rendered to us. He then said he going to try his best to assist us but also just played the fool with us with saying that on Friday the 13th with a call to say that we must pay a balance for the repair. My fiance again made his way to hifi just to be told that the difference not necessary as yet but when the device arrives. Today on the 20th of Nov they call once again about a quote, so what is actually going on concerning my device? Their service is pathetic they dnt give a customer information while you wait, and it's been a week now later that he said he will assit and still nothing! They called me on the 28th November to say device arrived as I'm fed up as they did nothing to repair it and was messing me around on when to pay for the repairs and I asked for device back, device arrived i checked it out and there was *****s missing on the device so now i will agian wait to hear what they say. They have a board in store about their promise to the customer if device not sorted or repaired with in 21 days it either gets replaced I waited in total 41days to know the outcome of this device and I'm very disgusted at their customer service as the manager at the store also could not keep his word in assisting us and want to blame the staff in the store. I was promised phonecalls that I never received on feedback nothing what so ever and when they called to pick up device at the time manager avoided helping or assisting us.I'm fed up as nobody taking this seriously. And I need my device as I'm a student aswell it really the last item I will ever buy from them. This was at the Baywest store in Port Elizabeth, I also asked for the area manager number but I was given excuses to receive it.
