Pathetic service

I have a hp spectre 360. In 2021/2022 my machine used to randomly get a blue screen error and automatically shuts itself down. My laptop was still under warranty and hp advised that Ensure Services can repair the laptop as its still under warranty. Within a year of the repair the same issue came back. I communicated with the manager at Ensure Services and booked my machine in on 14 February 2024. It was the worst experience ever. No one could give me full clarity of what's the status of my repair. I was always just told the parts are on back order. Numerous messages were left for the manager responsible but no courtesy call or feedback was provided from him. My machine eventually got repaired almost a month later. Within 2 weeks of receiving my PC it now does not go on at all. Their customer service is absolutely pathetic and yet the company boasts about servicing over a million happy clients. The senior manager himself does not even respond to emails. There has also been numerous complaints on various forums with the spectre and no clarity can be obtained if there was a recall on these machines or not. I'm am now sitting with a 'high end' machine that doesn't even switch on.
