Client card number than the one I was supposed to receive

I just received my first ever debit card yippie! But the number on my actual card is different than the one I was supposed to have. When I signed into RBC mobile banking it didn’t accept my actual physical card number, only the one I was supposed to receive. And now all of my banking info and money is on the card I was supposed to have and not the actual one I have. Please help.
