I need urgent help about my Uk visa application please.

I did biometrics on the 8th of September. Priority. I had three no straightforward cases and was eventually invited for interview, which I completed on the 15th of October and because of my enrollment deadline that was 16th the next day, the interviewer instructed me to contact my school to write Uk home office to confirm my ability to join them this October if my visa is approved. I contacted my school, explained the situation to them and requested for extension. My school emailed me after two days and confirmed that they’ve extended my enrollment deadline to 1st of November and had also written the home office with my updated CAS letter.

I did paid call first time today and I was asked if I had withdrawn my application, question was surprising because I wouldn’t do that and never did I mention anything like withdraw application in all my messages to them. The call ended and I called back. Someone else picked and after calling my reference number for him he also asked if I canceled my application because it’s showing that my case has been closed and not decided.

What does all of these mean and what should I do please?
