Indigo - Poor Indigo International Flight Service

I was scheduled to Board the Indigo International flight scheduled at **am from Singapore to Chennai on **th February ****.
We had read all terms and conditions regarding the flight, and even crosschecked our baggage weight *-* times prior to check-in.
During Check in, our baggage weighed ** kgs and we had put a total of ** kgs and had paid extra for the baggage too in prior.

The airlines staff now tells us, after a long queue of waiting for nearly *.* - * hours in line during check in, at ** am (* hour before the flight) that they wouldn’t accept our baggage, since, you can’t put ** kgs in the same suitcase apparently. The maximum you can put in is ** kgs in one suitcase it seems.

We were trying to explain to the airline staff that we had travelled just * months back in Indigo with ** kgs in one suitcase and there was no such rule, no rule is present in the terms and conditions too!
But the manager started shouting at us and said he can’t do anything if we didn’t read it clearly and was like ‘You can see around, no one carries ** kgs in the same baggage’.

Now, we asked him if there was any suitcase shops nearby, and he misguided us to go to ‘cheers’ to find a suitcase. Somehow we ran to the nearby shopping mall from the airport after asking a couple of people and bought the cheapest suitcase there for $*** and run back to the check in and immigration ** mins back!

Luckily, I’m a PR, so I have an auto-check in, in the immigration, else I would have to wait in line for */* hour and would have ended up missing the flight!
I boarded the flight exactly **-** mins departure in the final boarding call!

Since, they were so sure, I read the terms and conditions again, and no where was this written.
This is so ungraceful, and I have an exam in * days for which I’m travelling, will the Indigo Staff write the exam for me? Disappointing.
