conditional construction

[manhhiep2509]

Hello.

My problem is related to question VSC002819 in GMAT Prep pack 1.

(1) "Despite my boss's promise that if I finished my assignment on time I would get promoted, I did not get promoted at all"

(2) "Despite my boss's promise that if I finish my assignment on time I will get promoted, I did not get promoted at all"

Is the use of "finish" and "will" in (2) incorrect because the promise will not happen or is not a fact?

I must ask the question because I thought that the use of "finish" and "will" is wrong just because "I did not get promoted at all" has past tense.

Thank you.
