I couldn't open FB app after updation before * days. Then I uninstalled and installed again. After that I tried to sign in my account. But, I don't recieve two factor authentication code which I have given number. It seems change phone number without my approval. I tried many times. But still I can't open my FB account. Authentication code sending other number. Not to my number. Please help me to get back my FB account.
I trust that Facebook will make this right and come up with a resolution that is fair.
