Best Outstation Cab Service suggestion

Hi I am planning a round trip to Prayagraj (Kumbh) and ayodhya from Patna.(Patna -Prayagraj-ayodhya-patna) In coming weeks. Based on your outstation cab hiring experience can you suggest which company provides the best service and minimal rates? I have been seeing tons of complaints against every other company on the internet, so if you just share your experiences it would be very helpful.
