Sorry to reply quite late.
I needed time to figure out what's going on and also am confused what my resonsibilities are like.
Anyway, Mr. C asked T school to hold your final pay because you're deliberately terminating this contract within 6 months.
In this situation, why your terminating is called "deliberating" is you haven't showed any sign of change at work even though you have been warned several times for correction.
Since it was very important for you to cooperate with your coworkers to keep this job, you overlooked it intentionally and the school assumed that you have no willingness to continue the job.
Also, when it comes to the accomodation, it's provided by the employer not by your choice.
Therefore, Mr. C doesn't have the duty for your current apartment.
Right now, you owe him this month salary for the reimbursement.
This is the list of the details.
1. housing - 0.48 mil. (Jun.20 - Jul.31)
2. Visarun - 0.32 mil.
3. Replacement - 0.4 mil.
4. Recruiting - 1.1 mil.
It's from Mr. C's letter to T school and I'm delivering this details to you.
Please let me know if you have questions but unfortunately I will be away with my family till Mon., so there might be some delay of the response.
Sorry for what has happened and talk soon.
