How to cancel a service tax invoice if we had deposited service tax for that invoice?

can any body let me know what is the procedure to cancell a service tax invoice?

Ours is a limited liability company, registered under companies act and hold service tax registration. Our company has number of associate enterprises across the world.

Employees from our company participate in number of exhibition across the world to promote and sale our goods. If the exhibition is in a country wherein our associate concern is available, they help us in booking accomodation, transporation, exhibition hall, exhibition booth vendors, printing material, etc. and they pay for the same at that point of time.

On completion of the particular exhibition, they raise a debit note on us without adding any margin. It is purely a reimbursement debit note wherein all the supporting documents relating to above expenditure are enclosed.

I hereby want to know whether service tax will be applicable in our case under reverse charge mechanism, under old service tax law and under new service tax law based on negative list.
