Hi @Rali Videnova, welcome to our forum!
I'm afraid I can't really say much about the delivery service but I hope you've received the sim-card in the meantime.
Is this a replacement for an earlier simcard or a new simcard for a new subscription?
You can also visit one of our shops to get a new one, that's usually the quickest!
If you want to speak to our customer service about this the quickest route is by calling us on 0800-0402.
I can help you here as well with most things but it can take some time before you get a reply.
I havent heard from you so I'm assuming my colleagues helped you!
If you have any other questions you know where to find us!
