Sam's changed my Plus Membership to "Reseller" because of "too many addresses"?

Basically what the title says. Have had the Plus membership for about 4 years now and have never had an issue. I use the free shipping alot cause I'm disabled and am not always able to get to a store.

I also use the free shipping to send birthday gifts to family who aren't near me, so I have 7 addresses that aren't mine stored on my account but am only sending to other addresses a few times a year at most.

I renewed my membership on Wednesday and noticed later that day that items I regularly had shipped to me, no longer said "free with Plus". I can't get anything shipped to me for free anymore (even after meeting the $50 min.).

I contacted CS and they said that I have been flagged as a "reseller" because of "too many addresses" on my account. They had me remove the addresses but my account still needs to be "reviewed". Has anyone else encountered this issue?

TLDR; Sam's flagged my Plus membership as a "reseller" because of "too many addresses" stored on my account ( I ship gifts to out of area family sometimes) and now I can't get free shipping even with a $50 minimum. Anyone else had this happen?
