In the UK, the verb is get got got. UK: I have got yelled at several times. US: I have gotten yelled at several times. In addition, even in America, we use "have got" to mean "have": US and UK: I've got 5 biscuits on this plate. I know several speakers of British English who have a deep, visceral hatred of the word "gotten". They flinch every time I say it.

You can use "got" in those instances after a "You've" or "You Have" or "He Has" ... but the proper pronunciation is to omit the "got". It is an extra word and really serves no purpose. It is actually redundant. Example: A) You've got three years' worth is the same as B) You have three years' worth Both A and B imply possession of a quantity. However, A) is more of a lazy English I think? I also know that many folks in my area speak like example A) I just choose not to because it is redundant to imply possession twice.
