Air India — delay / cancellation of flight

Address:

Mumbai City, Maharashtra, 400010

An air india flight no. Ai 130 from lhr to bom on 15/09/2019 was scheduled at 1.15pm, then changed at the time of web checking at 3.55 pm, again changed to 2.30pm!!! More harraement as below.
There was total chaos at airindia counter at heathrow airport.. No proper guidance was available till 5.00 pm... Reason for cancellation of flight was given "rain in mumbai"!! And flight has not come from india!!! Ridiculous!!! Upon inquiry found that wheather in mumbai on 15/09/2019 was very much good!!!
After 5.00 pm i was told that you wiill have to take my baggages back and my flight will be tommorrow, means on 16/09/2019 and time will be approximately 7.00 am!!, proper confirmation will be givenafterwards!!! A senior wheel chair passenger like me was dissappointed... I asked about my rights under eu convention and asked for proper reply in writing but air india officials were not able to reply properly.. I asked to all persons at the counter including mr. Rakesh paul / mr. Sylvester/and ana marin... Found harrased and decided to go to one of my relatives place by cab... At the time of writing this i wish to mention my feedback which was sent earlier - no. Wb-ilhr[protected]
