i was given a wrong warranty contract for a laptop . A BRAND NEW LAPTOP that broke within 5 months

Good day i have an issue with a laptop i bought from Richfield it broke in the first 5 months and when i looked at the warranty it was not even meant for me as i paid cash and the warranty is more for students who received it free .. i was told my warranty voided when i opened up the laptop to see what's the issue was because the screen went black and the power remained on .. i just removed the battery and i also have a A+ Certificate to do so .. a new motherboard was installed and no reason could be given as to why it faulted . As per the college my warranty is now void even though the warranty was cancelling in December i was told its a 1 YEAR warranty

this is what i email to Richfield ..

Good Day Can the laptop issue please be resolved asap....i need a laptop as i am currently enrolled with online tutoring for Network Essentials for this month only I was advised that as soon as the new curriculum for next year is available then only I will be able to get a date for my N+ ... I don't know whether it's a new 3 months course or a date to write the examination. With all due respect I am still at the same position I was when I sent my complaint. I could have gone to pinnacle myself and shown them their mistake.. These are my issues.. 1: I paid cash for the laptop which means it belongs to me and not the college. 2. The warranty ends this December regardless. 3. The contract states for first year students or those for diplomas.. My stay was for only 6 months... And again I paid cash for the laptop... 4. I followed protocol and the power button remained on but nothing worked... I only removed the battery... And that is standard procedure as I explained to pinnacle and showed my technician certificate. 5. If that voided my warranty why did they still replace the motherboard. They couldn't give me a reason why the motherboard failed. My argument is what if it breaks again in a few weeks time. What then Surely if it was my fault then obviously it would have been noted. Still though.. Your warranty would have ended this December. I don't think you saw the Pic I sent regarding this. I even asked to change the size of the hard drive so I could feel somewhat satisfied with this.... I even offered to pay extra. Like I mentioned I didn't know what I bought and even though I asked to see the specs it was never presented... I was already a month and a half into my first paper and still had to wait another 2 weeks because it wasn't sorted out properly.... So when it came I had to just take it. My second paper N+ October-December and there aren't even books available even though I also paid cash.I had to ask for it to be postponed until next year because no one else would have done it.. And then within 5 months the laptop breaks... So can you imagine my frustration. And still my queries are being overlooked.. To show that I am at fault.. When the warranty is not even made out for me... I paid for the laptop... Pinnacle said you were not supposed to sell it to me because of the agreement they have with Richfield.... I'm not a one year student. I have a certified certificate to show I'm competent to open and fix computers with 10 years of experience... So I am asking cause I sure am not happy.. Will it be possible to return the laptop and get my money back.... Or get another, be it the same model but new.
