Bangalore Metropolitan Transport Corporation [BMTC] — Not accept online payment

Today my bike got some issue near by my office my office in ecospace so I get into bus no Ka57f2267
From sarjapura ring road to ecospace I not carrying cash so I request bus operator for online payment but he was denied for online payment and want 30 rs cash so I arranged 20 rs from another person but bus operator want 30 rs cash only. I given 20 rs cash and 10 rs I requested for online payment but he getdown me from bus on next station what going on with BMTC management why not accept online payment they don't want to pay Tax to goverment or anything else now a days even tea shop accept online payment so why you are not accepting need me full explanation because Our PM want to India digital and you are not accepting payments. Your bus operator insulted me on front of everyone only because I don't have cash and I requested for online payment. It's hurts me alot I need compansation otherwise I file a cash against you in near by police station
