Jet Airways — pathetic airline

Address:

Kolkata, West Bengal, 711109

I was travelling on jet airways 9w523 from riyadh to kolkata via mumbai. I had two infants, tried to book first row seat online (Service not available). Requested the customer service agent for business class upgrade (Not available), front row seat (Sold out). Boarded the flight, while conversing with a passenger realized that connecting flights to kolkata has changed. I dont think its fair to change the flight without notifying the passenger and that too if the flight change adds 7 hours to layover period. I was expecting 2 hours layover in mumbai and ended up staying for over 9 hours. No assistance was offered in mumbai. On top of this the staff treated me like it was free service.
