Prepaid Taxi At Howrah — Driving was rude

Today I travelled from Howrah to Joka. We were charged Rs 331. After that, the driver was asking for more 50 rupees for a short cut. We refused that.
We were informed that he can go inside joka uptp 500 metres. Before 500 metres only, he was shouting at me to get down.
These drivers shouldn't work for the prepaid services.
