If you remained civil and didn't threaten legal action then there is one more avenue to pursue. Your credit card company. Some find they can get the charges reversed and the dead product returned in such cases.

But if you were loud or rude or threatened legal action (more about that later) then you may have to wait it out.

About those that threaten legal action. We must be careful about that since companies have learned a new tactic. They can take you up on your threat. They'll check a box on their customer records you are going legal on them and then it's up to the lawyers and not a service issue.

Sorry to read about your woes but be sure to read every sentence in your warranty. Some do not have clauses about repairs in so many days or replacement laptops. Almost all push the data and files issue back on us. It is our responsibility for that.
