I have been with Twilio for 10 years. Never have I been so disappointed with their service. The following issues I have experienced over that last 10 years are as follows:1. Fax Service has been BETA all this time. Constant fax dropped calls or no fax at all.2. There auto-pay system is flawed. It will take and take and take to the point of your bank account being exhausted. No daily limits.3. Their Wireless IOT is very unstable for High Use devices.4. SMS were always hit and miss. The customer may or may not get them.5. There Voice TIWML scripts always had a high failure rate. If you build a script the speak command did not always talk or it sounded under water.5. There is no such thing as Anti-Fraud protection. In one day our SIP Trunk inbound had numbers calling in and showed 50 calls each at 3 hours, which accumulated over $3,000 in fees. Even though the account balance had no money available they just kept accumulating and Twilio's response was it was our system. However the calls never made it to or from our system. Even our fail-over provider did not have any issues from the unknown numbers.After this last instance, I am finally fed up with their crap, horrible support and unreliable network. We are up and moving to a new service.Always have redundancy as this will prove your company cares about its customer base. This is what our company has and getting rid of Twilio will be cost-effective and the sensible thing to do.
