when I recently got off KLAX and got the frequency change confirmed, I was not sent on approach, which was active, but with “Frequency Change Approved, Good Day!” Adopted. So I switched myself to the frequency Socal Approach. When I asked for a landing in KLAX, I was given a Frequnz change, which I did not ask.
After 2 minutes, I requested a landing for the second time, which led to a ban without warning.
What did I do wrong and why was I banned without warning?
