I have to award 3 stars, because ZOOM.US generously allows people to use their technology and software portal to conduct audio video communications for between 45 minutes and an hour - for free, but I have been very disappointed with their customer service as a fee paying customer. I won't pay for a second year.Brings to mind the line from Erin Brockovich in which lead actor Albert Finney asks star Julia Roberts if they teach beauty queens how to apologise, because, like ZOOM's customer service, they so far seem to suck at it.
