Cancel Large meeting Auto renew for next month, cancel billing invoice

[aungnyithit21]

For the large meeting 500, I subscribed the plan with one month plan for past months, when I need to use large meeting. But previous month zoom make large meeting plan for me about 10 days $17 to equal the zoom pro due date (26 th of month) . Now Zoom Large meeting is auto renew for next month.
I don't want to do this. I don't need large meeting plan for this month also I have not yet to pay new billing invoice for the large meeting.

Although cancel this plan, still have to give the billing, I don't want to pay for this invoice. Please support me for this issue, Thanks
