CAS for International Students

Hey,
I am an international student and am planning to attend Lancaster University. I had received confirmation of my acceptance in June, and my UCAS status had also switched to unconditional back in June. From what I understood at that point, my CAS for my Visa would be automatically generated and sent to me once the University had processed it. Moreover, I never received any communication from the University which instructed me about any next steps that I had to take. I know that some other universities require their students to apply for their CAS separately, but the Lancaster Website mentioned that it is automatically generated. It is now August and I have not received my CAS yet, nor have I received any communication from the university regarding this. I am not sure as to what is going on, and am quite stressed out about this as I need my CAS to apply for a visa.

I personally feel that the university hasn't done a very good job of communicating with their international students and have left them confused about this issue. I really am unaware of what I am supposed to do at this point.
