State Bank Of India [SBI] — Fastag issue

Don't ever go with a fast tag with SBI. They are big looters. Every year administrative charges are captured and the helpdesk is very useless, they don't have any access or authority. they have local agents to whom we have to contact for KYC, they ask 300. It will be activated for a year, again it is blocked, they ask to go to the agent again. The agent is asking for 300 rupees again to upload KYC. I am really frustrated with their service..
