Probably time to find another shop.

They don't know that brake fluid comes in crimson red. OK, so maybe they don't sell that type.

They can't tell the difference between a hydraulic fluid (oil) and brake fluid. Just need to rub it between your fingers to feel the difference.

They appear to have left air in the system. May be due to air in the ABS controller, may just be a poor job of bleeding it.

OP, if you trust them, ask them to bleed it again to firm up the pedal. If you don't, go to another shop with the same request.
