Yes, I hear what you are saying with open ears, and with shivers of recollection, because that was how Ameritrade used to behave, very highhandedly, before they decided to mend their ways, and that was why I left them. After all, individual freedom is at stake.
In the case of Zecco, they were behaving schizophrenically towards you, as well as being petty tyrants.
GL for better things now.
What really put me off with Zecco is that just a couple of weeks ago they told me there was no issue with either of these securities.
The non dtc list on Zecco is updated at will and it seems we can't do a thing about it. Bummer!
