Well, your first problem was investing in VW (KIDDING!). But seriously, I usually stick to self-serve stock purchases. Was this a situation where you had to contact a human to make the buy in the first place, or was it that you bought it yourself, then VW changed up their infrastructure and inadvertently locked you out?
Self serve, one one of those trading sites. No human contact, until the site wouldn’t let me trade the shares. I think the exchange changed up things and I am buying from another country so communication issues etc.
Shitty situation either way.
