Was just wondering about how and if you can get your account "health" up after a policy warning from amazon?

"We noticed that you have requested refunds for a large number of orders on multiple accounts because you reported that there was an item missing from the package."

30 orders have been made since this warning with multiple legit returns, any experience on getting back to the point before the warning or would it be wise to open another account soon? wanting to try and SE airpods max but wouldnt be able to do it on this account at the moment unfortunately

Consider those account linked/marked & flagged as "Concessions Abuser".

I belive SE on/through those "particular account(s)" will be harder now, you can prove me wrong, but that depends on your SE'ing skills. 

They do keep a track of REFUNDS they are issuing to you on each account, since the have said "REFUNDS FOR A LARGE number of orders on MULTIPLE ACCOUNT" so SE'ing on those accounts is not recommended.
Even worse? They might be able to track & link the new accounts you create. So be smart while creating new accounts too. 

Also if you try to keep SE'ing on THOSE SAME ACCOUNT(s) expect account closure sooner or later...if when you approach the AZ-CS-Rep both on phone & chat, 1st one will respond by saying there is dedicated team to handle this sort of issues & that they are transferring it to SENIOR TEAM which turns out to be there CAP(Concession Abuse Prevention) Team with "demonstrated history of denying claims" to customer(as per their linkedin profiles + the Convo i've had with them confirms it) & that team is used to dealing with RUDE+ABUSIVE customer(s)! 
^All these only because your multiple accounts are flagged! 

And also i think that CAP team Rep is able to see the GROSS TOTAL of refunds you've taken in recent history(how deep a Rep. can dig into your history depends on what LEVEL of job-post that PARTICULAR Rep is on but most of level 1 rep tend to transfer your call to their so called DEDICATED/SENIOR TEAM, if your account is marked/flagged as concession abuser!). 

ULTIMATLEY ITS YOUR CALL THAT WHETHER & HOW & WITH WHICH ACCOUNT YOU WANT TO PROCEED WITH YOUR SE!
