Waiting 4 months and they could not replace a faulty charger

DO NOT USE THEM! I bought an HP spectre laptop in January and the charger was faulty. I had to send the laptop and charger back even after confirming the charger did not charge my HP probook, but the probook charger worked on the spectre. They let me know on 16 April the unit is back with them, but they could not test it (they said they did not have the password, which I supp**** with the ticket - ERMA04944). You can go into the diagnostics to see the charger does not work, and you do not need a password for that. I got it back around the 20th of April, only to realise they stuffed up windows (my opinion it was deliberate) and the charger still did not work. I could not reinstall windows as they removed the files from the restore partition. They suck!
