I would have left a zero star review if that were possible, but Zoom gets one start here. My initial contact with Zoom for a United Pro plan was quite good. They had a sales rep contact me and even do a Zoom call to answer questions. I am impressed with the products they offer, so this was a tough decision to make as to whether to subscribe to their service. After the Zoom call, everything started to go downhill. I was never able to connect by video or phone again with my rep, and I ran into a bug with the purchase page on their web site. To get around this the rep had to push the purchase through with a E-Sign document and have my account that I created for the demo period charged.I needed to port a number over from another service and had questions about this. The only responses I got were links to pages on their site that explained porting. Of course I had more questions, but these were never adequately answered. On top of this, it always takes a full day for them to respond to my emails.After the service was officially started, we noticed that we were not able to assign phone numbers to any of the users, and the video meetings were limited to 40 minutes. It turns out the rep signed us up for the wrong service. After about 4-5 days of emails, we finally got the correct service working.Next came the challenge of porting our main company number. If you buy a 6 user United Pro license, you are able to assign 6 phone numbers. As you know, needs a main phone number, which is the one I needed to port from the other service. In order to configure the auto attendant and get all of the call ques set up, I needed to assign one of the user phone numbers as the temporary main number until the porting was completed.This begs the question: Why was there not a temporary main number already assigned? And why did I have to use a user's number to have a temporary main number? I don't know of one company in the universe who would use one of their user's phone numbers as the main company number!!!Now I have spend over a week trying to get a phone number assigned to the lone user without a number. The real kicker here is that you are unable to talk directly with anyone who can actually help you. They have a sales number on their site, but the person who answers your call here is about as good as an after hours calling service. They send a message to your sales rep and can't do anything else. I spend $1500 up front for 6 users of this service and I am unable to speak directly with a support or sales person! This is not only ridiculous, it is unacceptable!!The only reason I bought their service is because the product is good, but I am a hair away from dropping it if I can't do something as simple as add a phone number for a user. Something, by the way, that never should have been required in the first place!
