[Resolved]  HDFC Bank Fastag — hdfc fastag unable to reach anybody on toll free

Address: 560005

Uploaded all docs, made payment and sent signed scanned copy on the hdfc fastag link. No receipt confirmation no mail id, toll free not reachable is this a fake site?? Does anyone know who this matter can be escalated to. I have not been able to reach anybody in hdfc who knows that there is such a site. My hdfc branch on richmond road is unable to track any detail or person from hdfc for clarifications.
