New management or not shouldn't change the taste of the pizza if they are using company products. I would email corporate. If it was just a sloppy made pizza then I would start by calling the store and ask for a manager.
Yes they got new managers
I don't know. I've only purchased one time from papa Murphys and it was a good pizza on that occasion. I haven't been back only because I don't eat pizzas often (myself).
