Horrid support

I have a paid liscence.  I can’t access my old email so I tried to change my email address.  It says I need to access my old email to confirm the change.  What don’t you understand about unable to access old email.  Then I tried the online chat.  Told my liscence doesn’t accept the online support.  So paying close to $200 a year doesn’t qualify.  That is not acceptable.  Ok then I tried the phone support only to be told my paid liscence doesn’t qualify for phone support.  So I submitted a ticket only to find out that that isn’t even a priority.  I am part of an nonprofit organization.  The customer support is horrendous.  I am now moving our company to another platform so zoom will be losing several liscence.  How can a business survive with such horrible customer support.
