Good evening girls! I have a question about maternity leave. I went to yoga with a sick leave certificate and they said that pension payments haven't been made for the past six months. I am shocked because I worked, but it turned out that the money was sent, but the period was always the same, only May. Now they took a statement from the bank, I need to write a claim in the NAO in Astana, tomorrow I will deal with this. I am worried that all of this will take a long time, has anyone had such an experience? How long did you manage to get the money back after filing a claim?
