Astonishingly bad customer support for such a very simple request. This must be the worst experience I've ever had with any company. Zoom owes me 8+ hours of time back for something that should be a self-serve button in admin panel.I tried to cancel a service over a week before my company's renewal date, the bill would have been in excess of $1,000. I tried to cancel online but was told I needed to contact our company's account manager instead. I am then told by the account manager I need to e-mail the billing department who deal with these issues.The billing department simply could not be worse to deal with. They do not answer e-mails for weeks and when they do they don't seem to be able to read or understand the original e-mail. It took 10+ e-mails, 3+ phone calls and threats to share the situation publicly to get anyone to open my message. The billing team then responded over a month later 'to confirm that the bill I had paid 3 weeks prior was for the renewal' (note I was unable to stop the money from incorrectly coming out of my account). It was incredibly frustrating to have dedicated hours of time to try to contact them for them to a) take my money and b) reply with such little empathy and weak comprehension skills.It took several more days and multiple e-mails before I was told that as a 'one-time courtesy' they would issue a refund, and that in the future I should 'be sure to cancel my subscription prior to the renewal date'. This is despite the fact I had originally initiated a cancellation support ticket almost 2 months priorI need a lie down. I can now never recommend Zoom to anyone that values their time above zero.
