We finally were able to cancel our twilio account after 3 months of trying. The absolute incompetence of their customer service is astounding. After promising us a full refund multiple times they kept all of the money that we had pre-established in our account in anticipation of using their services even though they denied our campaign without any cause. Our campaign was a small internal one for our staff only. What a joke. I hope someone will start a class action lawsuit in CA about their cancellation policy. One click to cancel? Try 3 months and countless back and forth emails. Never pre-populate funds in this service. They will take your money. We still have funds sitting in there and they will not refund.
