I did not named it, since I was looking for callback from the company that acquired the failed broker. Wanted to add to the story… As it turned out, it was probably phishing scam. Very odd though, since they knew that I used the broker, they knew my first and last name and address. I never told anyone that I used the broker, so who was calling me- some rogue employees who withheld customer database after their company went insolvent? Anyway, googling of the phone number turned out some questionable things plus later I received unusual volume of scam calls.
People who guessed that it was SVS securities, were right.
