I would not have come if you could have communicated to me the change in the schedule. You were unable to get me through mobile is just an excuse, in that case you should have called me up on my landline.
is the above sentence structure is correct?
Please explain me why I am wrong, error if any?
It's not just a matter of tense; the correct words also have to be used.
1...You also could say '...if you would have communicated...', but "...if you had communicated..." is simpler/shorter.
2..."You were unable to get me..." is incorrect. 'That you were unable to get me...' would be correct.
my main concern is I want to know the proper use of woud / should / could, I generally get confused. So I am randomly forming sentences to know if my strudture is correct
