[Resolved]  MakeMyTrip India — cab driver using inappropriate language and sending threatening messages

I booked a cab on 3rd july from vit vellore to bengaluru international airport at 10 am. Due to some unfinished business i got late by about 90-120 minutes.in the it was showing total distance was about 213 kms but the route taken by him was of 253 kms which he took without asking me.
I missed my flight by 15 mins but i paid him the amount which was send to me by makemytrip on whatsapp in addition with the waiting charges of 120 mins. 90 mins after dropping me to airport he called me to tell that i had to give additional charges for extra distance which he travelled for which i said we haven't deviated from route at any point neither stopped anywhere for anything, still asking for charges for extra kms for which he told me to talk to his office. When i talked to them they said that the driver can't take the recommendated route because by following that route he had to cross andhra pradesh border and had to pay for permit, so i said you should have mentioned that in your website but his reply was to talk to makemytrip customer care. After about 30 mins later he started calling me for payment of extra distance travelled which is 40 kms but when i calculated i was about 20 kms which i told him.
Now he said pay by paytm or by google pay but i am unable to pay as i dosn't have any money left in my account and sent him a proof of that, after that he started using inappropriate language using my family members in it and threatened that he would post those messages on my facebook profile if i don't pay him the money which i don't have and asked him to come and collet from me in cash but he doesn't want to come.
