ak2000, how is your Rietumu account?
We are in a similar situation, after providing all requested documentation. Our income is very traceable and clean.
I have a suspicion that they are deliberately holding accounts frozen as long as possible due to liquidity problems. It's a real "bank run" for them, if all shell-companies, as they call them now, would leave altogether.
However, after 2 months notice of account termination, they are contractually obliged to release funds.. By 21st of May we shall see whether they go bankrupt (and we'll have to claim from deposit protection fund up to 100k EUR) or we are able to︀ withdraw full amounts..
