Paulo Travels — drunk and reckless drivers

Had a harrowing experience while traveling by paulo travels on 8.10.18. The bus stopped at manikandan hotel near kolhapur @11.30pm. After dinner me and the other passengers were shocked to see both the drivers totally drunk. There was a lengthy argument between the passengers and the drivers who were unrepentant about their act. As any replacement of driver would have resulted in a lot of time loss i decided to take another bus for mumbai.
I called up paulo travels manager the next day who told me that refund was not possible as another driver was arranged for at the restaurant. Dont know how they managed to find a responsible and competent driver at the hotel o. Are drivers appointed on the spot without checking their credentials? Lost all faith in private bus operators after this incident.
It is extremely alarming that people blindly trust such travel agencies who do not appoint responsible drivers on such hazardous and accident prone routes. All such issues are settled and swept under the carpet. Please do not put your life on the line by traveling by paulo travels.
