KFC India — charges for the item sold

We had been to kfc outlet situated at new delhi airport near terminal t3 food court. (Near pillar no. 17) on 24th may 2018 to buy some food items.
The rates displayed there do not mention whether the cost includes gst or not.
When i asked why it is not clear, the sales girl or the manager of the outlet was also not aware about the same.
I have written complaint about the same on 24th may 2018 at 2.30 pm.
The manager mr. Karan told me that i will get feedback/call from kfc office within 24 hrs. But till date, i have not received any call of feedback from your office.
Pl. Look into the matter and try to give feedback on time as promised.
Regards,
