***** on my account no help from FNB

Received the worst service from FNB thus far. They allowed someone else to use my cell phone number which has access to everything on my account. I was put through to the ***** department which apparently delink the other person profile however they still using my freaking number.

How is it possible for one system to use the same number didn't they need the otp pin from my number?

I had to change my number, now they suggesting I just dont use my own focking number. Cause they can't see who I using my number. How pathetic.

Im so annoyed right now, idk what I'll do if my salary gets paid into my account.
