Im trying to get my contacts from a whatsapp account i made while i was overseas, I no longer have access to the phone number and was just recently force logged out because someone else was most likely assigned the number. I never deleted the app on my phone though and am still getting the screen where it asks me to log back in or ELSE ill lose all my back ups so im assuming my local data is still here. Can someone please help me, all i need are my contacts
