Scam

I have received a call from a lady claiming to be from blue label/bigworld mobile..she told me i qualify for a cellphone,she took my personal details including my banking details but first she needed to confirm more details with my manager till today she hasn't phoned me back...I think i have been scammed, I can't shake the feeling,"the cellphone was supposed to have arrived today 29-07-2020..the number she called me from no longer exists
