Air India — delayed flight over 8 hours

Hi
I booked flight from stockhome to delhi on 6 oct 2017. The flight was delayed like more than 8 hours and my meeting which was held postponed because i reached delhi in afternoon 1 pm instead of morning. So i am looking for compenstation for this delay.
Also when i took flight back from delhi to gothenburg.
My baggage was cheked in delhi and assured me that i will get it in gothenburg.
While waiting for my flight in stockhome i got a call from sas collaboration partner with air india that i need to check in my luggage myself if i want it to reach gothenburg today.
Then i again rushed from domestic terminal to internation terminal took my luggage and checked in.
It was a horrific experience for me while travelling with air india.
Even you dont have any option for web check in if you are travelling from stockholm
