"I’m begging you, please check my newborn "

Missed my child 8 weeks check and vaccine. We called them for a month and every week we call them. Until now, my child is 10 week old, they still say they will call us back on the day we called them ( which never happened). Can anyone suggest us what to do with my child vaccine and 8 weeks check? As how can we get it done? We are depressed and stressed about it. Especially they keep saying they will call us back. But it’s been a month, we never hear back anything.
