Pizza Hut India — Employee vulgar language usage

I had ordered a pizza from city center mall Gurgaon
Take away delivery

I reached the outlet on time for collection and the order was not ready
I asked the reason employee with contact number +91 [protected] and he said we are short of staff and will take another 15 minutes to get the order ready
Hence I wanted to cancel the order and it turned up to a arguement and he started using vulgar words

I need company to take necessary actions else I will file a complaint in police station
