password and my payment

I checked my  inquiry, but I could not find my inquiry I had posted not long ago.

I ask you again, I paid 1-year payment some months ago, but a message that asked me to change my password was popped, and I changed my password. After some hours I tried to open my zoom meeting as usual, but it was not open. Then I tried to open my zoom meeting with my new password. While I was using it, a message was popped, and it asked payment to me. I was disconcerted. 

I have many chances to use my zoom meeting. Please settle this problem quickly.
