Well water system not holding pressure after main line was broken.

I just had a company come out to waterproof my basement by putting a drainage system inside. While they were busting up the concrete they busted thru the main inlet line coming from the well pump and broke the wires. Their plumber came out and repaired the water line and wires but now my system won’t maintain pressure.

It will go over pressure, then it sounds like the a ton of water and air flow through the lines and then it will lose pressure for a few minutes and start again. Any help is appreciated and I can answer questions as best as I can, I have some knowledge but not much pertaining to well systems.
