When you outsource your customer support to a call centre where the people there have no power whatsoever to actually help you, who are just trained to get you off the call with a "if there's anything else we can help you with...", why bother? Support needs to be in-house, and the people doing it need to have the power to actually do something when you call them. Otherwise, it's just for show, it's ticking a box in some compliance or PR checklist
