@MrYakso World keys are hard coded into the game which means there is the possibility that the help center can't help you with the missing key since they really are not able to add world keys to an account.
If that is the case I would take what they offer you for compensation and wait for the next update that fixed the issue (this will probably take two month).
I'm sorry they couldn't help but the devs know about the bug an they are working on a fix.
We think EA HELP is an Indian call center and possibly badly affected by the current outbreak of the Wuhan flu, normally they say that they will give a response within 48 hours if you create a case by email, which is ordinarily the way pvz2 complaints are dealt with but if you tap EA HELP they are now doing complaints by phone, which is a new thing in my experience of dealing with them for over 2 years.
