Hello girls. Who returned 42500 ten period of CP which were appointed, I received all payments for the period of CP and now I am filing maternity leave and they ask for an order that I did not work during this period, we are IP and I also deposited pension and Soc. And it turns out that I seem to have worked during this period, What should I do now? Anyone who returned 42500 and for what period? How many times do you return? Damn head spinning. Kazakhstan.
