Bengaluru Metro Rail Corporation [bmrcl] — False payment

Address:

Rn.12, s.m road, opposite to new krishna hospital, near rock line mall, jallhalli cross, banglore - 560057

The ladies sitting on the recharge counter of jallhalli cross metro station, I guess they have lot and lot to talk about their life. on their workspace, so careless that they put extra money, I told to to recharge for 100 they allegedly put 200. Is BMRCL going down in loss, so they are using this strategy to gain money. Kindly solve this issue, or if I face next time I'll sue you guys for sure...!!!
Keep this noted.
