I have recently separated from my ex and claimed HB. A couple of weeks ago, a lady from some official organization (didn't get the name, but I think it's the council) called me to ask questions about my daughter, said I should take her for medical revision or something like that (again, I didn't understand it very well, English is not my first language). She said she would send me a letter with the details of the appointment, but I didn't get it and so I didn't go. Today she called again (from a blocked number) saying she would come to my house tomorrow (?!) and asking me if it was OK to bring a student with her. Does anybody know what this is all about? Should I be worried?
