I tried to ring back the number (02) 4208 0351 but reached a silent voice mail

This number called. I didn’t answer as I was driving. Caller didn’t leave a message so I will not returning the call

I tried to call the number but it was engaged

The caller had my dob and said that they had my credit card with first number and repeatedly asked me to provide the other number

Female foreign voice. Gabbled so fast I could not make it out. Then she said, “Your date of birth is such and such and your email address is such and such.” I said no and hung up.
