Bug them if you wish, but unless you open an account with ETrade or another brokerage that allows you to buy and sell it, you are losing time, and time is money, they say. Transfer some funds to ETrade if I were you. It only takes minutes to open an account and transfer funds and then you would be good to go.
They are not going to 'fix the problem'. Get with Etrade or another broker that will trade them, IF you want NSAV shares. Bugging them will not fix it. It is a corporate decision that will only change when they are forced to, by trying to uplist, etc.
