Extra charges & account not updated corrected

I have spoken with the multiple people but the wrong email and address are still showing on my account. I keep being told the situation has been resolved yet months later I find the issue still hasn’t been resolved. 
Also, I keep having international charges on my account from a trip I took months ago. I expected a high bill for 1-2 billing cycles after my trip, but I do not understand why one bill is normal then a month or two later I see more international charges. Please remove these extra charges from my upcoming bill.
