GoAir — ground staff and policies

I was travelling from srinagar to delhi on the 6th of aug, 2018 and had a connecting flight to catch to dubai the same day. I had excess baggage according to domestic standards but i was carrying baggage in compliance with international flight allowance. Almost all the domestic airlines i have travelled in so far have considered the within 24 hour international connection and wavered the extra luggage, but goair staff refused to oblige.
My uncle, who was also travelling the same airlines, walked in five minutes after me and we wanted to check in together but a certain rahul sharma started shouting that pooling is not allowed. I don’t see how checking in with a family member is called pooling. He went on to point towards me to the rest of the staff as if i was a culprit.
Then as my uncle was asking another ground staff member as to why we were not allowed as a family to check in, he (Mubashir nazir) shot up from his seat and started howling at my uncle and told him to get out of there.
I complained about this to the manager, who kept apologising for that man’s behaviour but neither mubashir admit to his dishonourable behaviour towards a senior citizen nor did he show the courtesy to apologise. A galore lack of training in how to behave with customers.
The manager had promised that action would be taken against the staff that was rude. The least i would have expected is a written apology to my uncle, as well as training for better management. I am still awaiting any indication of either.
