Good morning, could you tell me… I was not given a certificate that I did not receive a baby box because I got married and my passport is not changed, they gave me a ticket late, in the passport there was a stamp for two months saying it's subject to replacement, at the hospital they said if you make a passport within a month you will come and take the certificate, it can be picked up within a month, I couldn't make a passport within a month, so I didn't go to the hospital for the certificate, my friend proves that this certificate can be taken from them now, as I have to get this box or money anyway, has anyone had such an experience, what should I do?
