[Resolved]  IDFC Bank — fastag login related

I had recived fastag from bharthana tool (Vb tool), near karjan. I had received fasttag from tool plaza and i had received log id & link by sms on my cell phone no ;[protected] that time. When govt. Make it compalsary that time i triy to log in with received id and password but i cannot got login, it says your id got expired. So i tried to contact idfc toll free number but not responding. I cant opt for other app without cancellation of this app. So how can i get login to top up money or check my balance. For top up i have to go tool plaza and your person topup it. But i cant go every time to top up at tool. My vehical no is gj 4 ap 1534.
