Air India — customer service advisor error at chandigarh air india office

Address:

Chandigarh air India office, Chandigarh, Punjab

Visited chandigarh air india office to change return ticket date for spouse only and to leave my return date as it was. I handed passport and details for my spouse and realised when i got home he had changed my return date as well. Next day when my son went to complain about this error made on their behalf, i was charged £125 for changing the return date. No charge was applied when changing my spouse return date. Cannot understand why my return date was changed when it was made clear to advisor.
