is not stamped in your passport you could be in trouble.

The company could decide either to send you back and blacklist you (meaning a 2 year ban on you) or in the worst scenario file a complaint on you for "absconding" and then leave the case to the authorities (jail, trial, deportation and ban)

Regardless of the case or the scenario you should have had all contract options and conditions clear before even coming into Qatar. There is no way the company is going to change the conditions once they have you here already.

Hope the best for you!!!
