Samsung Issues Deluxe

My Samsung J7 Pro had a software update that was done on the 20th of December and it was downloaded without any complications and any interruptions, But after the device started again it gave issues like that the screen was working but there was no reaction to touch. So I took my Samsung to the Samsung Store in Somerset Mall to get it fixed. But was then informed due to a small crack at the top of the phone (had no influence )the warranty was no longer given. I said I will pay for the software to be reloaded and hope that resolves the issue. Also, I was told that it would take 2 weeks to sort. But it did not happen the phone was sent to Wefix in canal walk and the communication was not provided and the two weeks went past and no news so went to the Samsung shop again to ask what's going on to be told that they busy uploading the software but all is good. then 3 days later went back and suddenly the technician left on leave and didn't finish my phone and issues began. Since then the phone was apparently no longer working and after driving for nearly a 1,5 weeks to Samsung shop each day and calling them nothing has been happening till today when finally the call came and they just said the technicians just said that my phone is off warranty and that Samsung will not replace it. and the costs are higher to repair it. It is interesting how a phone that was working perfectly fine before an official update can suddenly be so broken that it wouldn't be fixed. Also to Add Samsung refuses to have written communication so seems they hiding things and also interesting enough no reports are provided to me as a client
