[IE] Lady asked me for my phone to call someone.

A lady asked me for my phone to make a call. She was a bit older so I thought she might really need it. Anyway, she goes on to dial some number starting with « 17 » and then my phone beeps, then deletes the number from my call logs. Then I checked my bank info & typed the codes to cancel call forwarding etc. is there anything else I need to do? Is there any way my info was leaked? All she did was dial a number and then I took my phone back. I am quite worried.
