I work in company x and my role require that I have to work closely with company Y.I am a contractual worker and I am supposed to complete my project within the stipulated period.However I have not been able to hit any of the deadlines,since company Y is a blocker in a way that my job would only move on if they submit certain projects to me.I have written a lot of emails to them to let them know that we are in a time crunch.I try to give them a sand-witch feedback whenever they revert back to me.I let them I know that I understand their busy schedule,however my team awaits the result of this project.
They give me timelines which they never meet.They do not communicate the progress of the project.This has a led to a lot of distrust in my ability to deliver.There are chances that I could get permanent employment in this company x,however,with all that has been happening.I stand a little chance to have this opportunity.
How do I get this company Y to stick by their words when they commit to deliver at a certain time?I feel that they don't respect our agreement at all.
Kindly guide me through how to also explain to my company that this project also depends on how company Y deliver to me,Without looking like am trying to blame other people.
