Partserve's pathetic services

I had sent in my Acer laptop for repairs (Durban branch). They had taken a long time to first let me know that it will be repaired, after no communication for a while, I called again to find out that they can not find one part for the laptop however, they have the other parts that were needed so I had asked if they could do without the part and try to get it fixed, I was told that the technician will try his best to get it fixed without the part which they could not sort out, which I thought would be great. I had also asked if I could speak to the tech and I was told that the tech was not around so call on another day and when I did, I was then told that they are trying to make a plan to sort it out. Some time later I was told that it can't be fixed and I can fetch it. When I received my laptop, it is now in a worse off condition than when I had sent it through. I was using it all along and there were no issues except for the parts that needed to be changed due to a lift on the top casing. Now I will not be able to use the laptop at all, as this top casing is almost completely out on one side. I was very clear when I said that this laptop must never be closed as it will cause further damage. I received it closed! It gets worse when I call the branch manager, Alton. He has no idea as to what my laptop looks like but from reading the description he insisted that because the job states that the hinges are broken, it is time I bought a new laptop. I tried to explain the before and after condition but he refused to understand and spoke on top of my voice. It was no decent conversation as this man is ridiculously uncivilized and insisted on my laptop being unusable due to the damage his reading off his laptop, yet I tried to explain that I've been using it all along but now I cannot and it's the fault of Partserve yet he insisted otherwise. Why would I even send it in if it was not damaged, because he was very quick to scream out the issues with the laptop, some were even the scratches on it, which I cannot even see on the laptop but he made it seem like scratches would cause such a drastic change to it's real issue. Also, he said that it was noted that I declined their quote which was a first to me, since I never declined and was ready to pay any amount after the repair. I am utterly disgusted by Partserve's work and this manager. He is by far the most disrespectful man I've ever dealt with!
