Super shady, SCAM company. Unbelievably poor customer service and communication. I've been trying to lower our plan since February 10th, but they just ignore me. They keep taking more money than they should, without any care for their customers. Their customer service is a ghost - nowhere to be found when you need it. Fancy ads and promises mean nothing when they treat customers like this. Warning to anyone thinking about using Aircall: be ready for severe headaches, wasting hours of your time to no avail, and a bleeding bank account that you'll need to chase (with no apparent resolution either, you might have to escalate to your bank / authorities). I'm literally trying to stop them from charging us further and somehow get our money back but can't get responses out of them.
