If you use Mainstar, you don't own your shares
Cancelled my direct registered shares after being directly registered, then subsequently blamed this on the transfer agent Computershare. Mainstar does not have your best interest in mind & will manipulate your holdings if you are not careful - your holdings are not yours if you are keeping them with this "Custodian". Withdraw your shares & re-purchase them through the transfer agent, you will be the sole owner of those securities & bottom feeders like Mainstar won't be in a position to play around with your retirement.
