Passing the buck

So I bought a MacBook Pro, 1st they give me a device that’s locked to their users, and refuse to help me till I go back to the store 100km away, then they unlock it and now it needs new software, they install it and 1 mo Th later whole laptop has an OS glitch, I go right back to the store and they want to waste my time with booking when I want a copy of the OS to do it myself coz obviously they are giving me ****ty service as is
