Nextiva vs Zoom Phone

So From the CRM to the Mobile app everything has bugs and problems. The mobile app does not work and they want to blame your router. So my router at home, my router at work, the router at Starbucks, the 4G form my cell provider. They keep you on the phone to try to fix the bugs and trouble shoot for hours at a time for an app that is not yours to begin with. To then nothing resolved, and try again next week. They don't care that you have a business to run and want you to help in the " trouble shoot and try to fix it ". In the mean while you loose business because you don't get your phone calls either the app does not work or your on the phone with support .They don't understand that for a small business it is our lifeline. Don't waste your time or money, unless you actually want to loose your business. I have spent thousands of dollars to do marketing for my company for the mobile app to ring and dead air, because it does not work. SO when they look at the analytics they say "you received 270 phone calls last week" but fail to look at the average call being 4 to 7 seconds in length. STAY AWAY From This Company nothing but headaches and problems!!!!!
