firstly i feel you, i liked the original poswallet very much as well, but since it was not profitable, there would have been no worse decision than not changing anything
secondly, the limits have been in place since i joined psowallet back in january, so that's nothing new, as well as their office hours. I personally never had a problem withdrawing, but i never tried whilst they were working on some security measures on the page
thirdly, since i was anticipating the changes that poswallet undergoes i withdrew my money before the weekend.
and last but not least: i doubt you could have sold for 5-6k unless you would have had them in a sell order already when the pump happened
