I am working with a properitorship firm from nov 2010, when i joined i gave an undated check with x amount, the bond was like they will drop the cheque if i leave the job before 2 years, i want to leave the company now because of some false promises made by them regarding my salary, i dont know what will be the effect of the cheque which i gave, please show me a clear way to get out of this. I recenty cancelled the whole claiming that i lost it cheque.
