Shocking service at Game

Absolutely shocking service at Game Pavillion. I bought a laptop at Dion Wired at the end of January 2020. Dion Wired obviously closed and Game took over their warranties (which are valid for a year). They took it in for repairs and kept it for over 3 months because of 'the lockdown'. They returned it last week with some charge in it and it worked for a day. It now refuses to charge or even switch on. This was the initial problem that I took it in for. They now want to take it in for repairs and absolutely refuse to replace it. I am so fed up and in tears
