I'm afraid that--if you can't answer your security questions or provide the correct recovery phone--you're strictly out of luck.
These mechanisms are in place for your protection. If you're going to bat .500 or less on the vendor's attempts to verify you, would YOU reactivate the account if you were in the vendor's shoes?
Offhand, it sounds like the account is sufficiently stale that it won't be a major inconvenience for you to write it off and establish a new one. This time, please read the account conditions VERY CAREFULLY (I know most people don't: they just check the box and say, "Yeah, whatever") and choose security questions that you can answer and phones that you won't disable or misplace. BTW, a misplaced phone can READILY be replaced, and the new phone attached to the original phone number.
1. This is not a hoax.
2. Remarkably, technically challenged users who DON'T LIKE WHAT THEY'RE HEARING--even when it's the Lord's truth--traditionally suspect a HOAX.
3. We recently won $25 million in funding from Mr. Charles Schwab--the man himself, not even the company. I dare say that such captains of industry perform their "due diligence" checks before throwing money around. We maintain A+ ratings with BBB and other cognizant ratings councils.
4. The advice still applies. If you cannot remember your security questions and/or maintain a working telephone, you will encounter problems with e-mail accounts. This is for YOUR protection. The ISPs are being reasonably patient, and even more so. They have zero LEGAL OBLIGATION to provide you with e-mail services, and all they require from YOU is a permanent phone number and a handful of Q&A THAT YOU CHOSE.
