\Given your geographical location, running 0w-20 in lieu of 5w-30 gains nothing, and given your particular application (nothing out of the ordinary about how the engine is operated), running 5w-30 over 0w-20 gains you notihng.
In other words, for all intents and purposes, you can consider the two oils to be effectively the same. Move onto the next problem in your life and work on resolving it; as this one is not a real problem at all.
For all those that responded with, "Take it back and make them do it right!" or some version of that, I have a serious question for you: Really? Is that what you would do? Why? It won't make one single bit of difference in how the vehicle's engine operates or how long it lives. So what's the point? To teach them a lesson? To right some perceived wrong?
I envy anyone that has the free time to waste making others redo tasks which were done without any effective problems to begin with and yet must insist on being done again just to satisfy some warped belief that the world has to be completely fair and and orderly merely because they want it to be.
Everyone has issues in their lives. Dealing with the important ones first is what matters. Despite what others might say, worrying about running 0w-20 versus 5w-30 when you drive around in the southern continental U.S. is not something to worry about.
