Don't worry. If the lady said that, she will very most likely be working on it.

The reason you didn't get a regular telephone answer most likely is exactly because it is the social security office. They do that for privacy. If they call you at your number, and then anyone tries to find out who you just called, that person would be unable to know what business you have with them. It's about privacy for you.

Sadly, our health systems are swamped with tons of applicants, new and ever-changing laws, and sometimes the letter does not coincide with the time you talk with someone working there, or vice versa. The lady may not have entered into the computer yet what she told you about the back payment.

Still, keep in touch with her, while also not nagging her. Just make sure she keeps you informed and the two of you stay in touch. Ask her when she will be sending out a letter...

This is normal sounding. Just stay up with it!!
