TVS Credit Services Ltd — complaining you tvs credit mobile support desk

I found some problem on tvs saathi app. I talked mobile support desk mens that help me on to work saathi appa. But when i call no [protected] then one person pickup and speak rudely to me. Then i asked some errors found on apps so kindly support me. But that person not listen anything and just force me to paid emi of mobil. Then i said i am not perched mobile, i am perched bike from tvs credit. Then that person shouting.. Don't call this no. Go and scearch on google to find for bike customer care.
That behaviour was very bad for me...
