I payed for a Zoom Pro account, which after slightly more than one month of usage I wasn't able to login anymore (since the Google login into Zoom was broken). Until that point I was happy with the product. Then I tried to contact the customer support, which needed 7 (!!!) weeks of waiting time for the first nongeneric response. On its website Zoom promises response for urgent requests within 1h. At the end, the Zoom customer support could only close my account and reimbursed only part of the money I paid while the account did not work.For a paying customer this is beyond anything that I'm used to from a tech company - in terms of response time and in terms of honesty towards your customer.While the core product is very good, I can't recommend using it in any professional environment for the lack of customer support. If you are using the free version or don't ever need any customer support, then you might be happy.
