We got our vaccination done today at Global hospital Patel and were told that vaccination certificate would be received on line.
We have since received SMS intimating that certificate has been generated but can be downloaded only with a 14 digit beneficiary reference ID which we do not have.
We are requesting hospital to provide us this. However every time I call them they ask me to call later. Now they are disconnecting immediately on hearing my request
Please help
