can the company or agency cancel my tourist L visa

Hi,
My company/agency provided me a one year tourist L type when they promised me a Business M type. I stopped my contract with them because that's not our agreement.

Now they still want me to pay the 5000rmb fee for this. I refuse and they threaten me with cancelling the tourist L type.. It's even possible to cancel it cause it's already in my passport and have it with me here.
