Did they also say "on a recorded line" ? NEVER ever answer "Yes" to ANY such a question, they will record you saying "yes" and insert it into their recorded script to say that you have bought something.
If you even answer, say something like "I hear you loud and clear".
Who does the number 704-228-8222 belong to they have called me 3 times just now. 4:31== 4:34== and 4:37 .. they don't leave a message. And I don't answer my phone if I don't know number.
