I finally got Supervisor Number Three to understand what was going on, and he gave me an entirely different phone number to call, which ended up being their corporate office in India. After talking to three different people there (again, "escalating" laterally) I ended up with someone who claimed to be the director of support, and she was able to unlock my account and allow the port to complete. She said that she had never seen a situation like that before, and assured me that if I ever came back to Straight Talk I wouldn't see this issue again, as they would "fix the porting process" to enable their Tier 1 staff to push the port through.
This entire process took three days of calling from my wife's phone, since mine was in limbo and unusable on either service, and probably shaved several months off my lifespan due to the stress and anxiety over the whole thing. One thing is for sure, I will never, ever use Straight Talk again, I don't care if someone gives me a $600 Straight Talk-compatible phone.
In comparison, on Ting, I call their support line and within three rings I have a real person who has full access to my account and can do pretty much anything I need to with it. Just out of curiosity, I asked a Ting rep how the cancellation process goes if I wanted to go to another carrier, and he said they would help me make the transition as smooth as possible, and would hate to see me go but he wouldn't want to hold me back if another carrier offered better coverage or rates.
Comcast, Straight Talk, and other service companies could learn a lot from them.
A correct response to a unsatisfied customer would be: My supervisor doesn't talk to customers. I am the support for the company, if you are not satisfied with me, you can talk to a different operator or file a formal complaint.
This is an actual correct response to a conversation that has gone awry,( of course again, assuming the operator is behaving like a decent human being ).
