When I wanted to downgrade I sent a ticket and was sent this link

One thing I forgot to do was remove clothes from spare VIP heads. So remember to do this! If you don't, you can't put the head back on, to remove the item of clothing. I had to get a VIP friend to help me after I downgraded.
I also added someone onto all my turf leases in case it all went wrong. It didn't go wrong thankfully.
Hope it goes smoothly for you.
