This happened because they bled the brakes the wrong way, not your fault mate they are responcible for the additional cost, not you

Nor me, no guarantee of the seals seating back unless a complete strip down, also you'll lose the clutch too as they share the same master cylinder.
I think you mean "fluid reservoir" not "master cylinder". The brake and clutch pedals each operate their own, separate, master cylinders. There is one shared hydraulic fluid reservoir, and so only one place to fill with brake fluid when either system needs a top-up.
Oh & going totally off topic for a sec...I did get my new Wheels fitted on Saturday , Will send you the pics when the weather's better & I can give them & the car a quick clean
