No customer loyalty
We started using Aircall in 2015, when they first launched. The pricing has changed multiple times as they grew, and we ended up 10 years later on a yearly plan. The website currently states that you need a minimum of 3 licenses. We were on a plan with a minimum of 5 licenses (so worst off than new customers). When asked why this was and if we could change (we don't need 5 licenses) we were told "our plan has a minimum of 5 licenses, and we need to wait a year before changing this". Thats 28€ * 12 * 2 = 672€ which we lost this year. If you want a company that clearly does not care about customers, not even the most loyal ones, than Aircall is for you. Meanwhile we have switched (like plently others) to Allô.
