Your period of engagement as ‘Trainee’ seems to be from 02-09-13 to 02-09-15!
There seems to be an error as you won’t be completing 8 days by 10th Sep,2015?
Since how long (months) you are working with this company?
What would be your tenure in months by 10th Sep,2015?
You seem to be rather completing 2 years by 10th Sep,2015, and the training would end on this completion of 2years, then what is the issue? Moreover after completion of 2 years since training would end and you have no right be absorbed in permanent employment then no notice is required to be tendered by you.
The state of Kerala has covered IT employees under Min. Wages Act.
You may check the notifications issued by o/o Labor Commissioner and compare if you were paid Min.Wages or not?
