we received a call 3 days before claiming to be from Fido marketing team offering Us some good promotional plans to get us back to Fido. They had all our account details including the credit card's last 4 digits we used last time and the last 3 digits of the Id proof we gave then, my address etc. We were given some sweet deals which we accepted. They asked for two id proofs to confirm the process and we have the numbers for DL and COPR. They didn't ask for any payment options m, credit card numbers or so..
the woman who talked to me said that we will be receiving a mail from Fido confirming the offer we are getting, the connection details and such within 24-48 hours. It's been three days since this and we never got that mail.
How can I find whether this was an identity theft scam or so?
