warranty scandals

I bought a brand new polo vivo 2022 model at VW Hatfield in August 2022. on Friday the 13 June 2025 my husband was washing the car outside our gate, he then drove the car in the yard after washing it parking it just outside the garage. moments later when he was done cleaning the car inside he started the car to get in the garage but the car wouldnt start. he thought the problem was with the battery because the car was ok just a couple of minutes ago. the was already an EPC light on the small screen or whatever they call it, he however thought it was the battery and then he jam started the car correctly, positive with positive and negative with negative, but the car wouldnt start even after. he pushed the car inside the garage and we decided to see what will happen the next day. on saturday he attempted started the car, but still nothing and he did not understand what could be the problem and this time it was not just the EPC light on the screen but an engine light was now on. i was the one who even mentioned it to him that there is another light, he told me it was an engine light. he opted to call his colleague who has a work shop to come diagnose the car, his colleague only came sunday and the report he sent to my husband indicated a lot of errors on the car, report which we have and cannot attach here. i texted th sales lady who helped me buy the car on monday 16 June 2025 and she advised me to call the branch since she was no longer working at that branch. i called Hatfield VW on Tuesday morning and they informed me to call VW road assistance, i did and the car was towed. they called that very day to say the mechanic will give me a call to advise what is the problem with the car once they have diagnosed the car. they called me only on Thursday in the morning, they mechanic wanted me to explain what happened which i did. later now that day around 4pm i receive a call that warranty wont cover, the computer box was damaged when we were jumping the car, we did not do it correctly. as expected, this was bound to happen, our daily story when it comes to manufactures having to repair a damage under warranty. firstly the car was not starting even before my husband jump started the car, he thought of that after a while trying to start the car and he could see it was not starting, secondly the was an EPC light before he even thought of jumping the car, thirdly we are very certain he did it properly but the car was not starting even. the dealer is informing us that the computer box was damaged because of the jumping however the car was already not working/starting. we have the report and we would like them to prove to us in writing and share the report of what they are saying. we are now suppose to pay +34k for a car that is not more than 3 years, that i still under warranty. this is a problem that most consumers are facing everyday when they are suppose to be assisted under warranty, the manufacture will try and deny and find fault on the consumer's part, we are powerless and do not understand nor even know this things which is easy for them to get away with it. this is a fairly new car, my husband is always careful and i can assure you the car started having the problem even before he attempted jumping the battery. we need proof and we need to know it can not be covered in writing as we are not prepared to just let this go.
