Do you see why we both interpreted the sequence of events as you being okay with it though? They asked if they could, you asked me if I was okay with it, I said yes, and you gave them my info. Could you see why your doing that would make it seem like you were okay with that, vs if you had said 'actually wait, I'm not okay with this and I have some questions' or just saying no? I think both your case manager and I would have been fine with you saying no or asking questions, but you not saying no or asking questions and just giving them my information and voicing no concerns made it come across as you being fine with it. Does that make sense? It's okay to say no and ask for what you need!
I hope this week goes better and I really hope you're able to ask your case manager for appointment info and more support if you need it.
