Financial complexity

I have a subscription to Zoom.   I think it is about $17 a month.  Recently I was in a session and got a message telling me that my 45 minute limit was being lifted for some reason.  But I have a subscription!  I don't have a limit!  Or do I?  I am having a lot of trouble with this service.  (This isn't the only problem.)  How do I get in touch with a real Zoom help person?
