called to ask for last 4 digits of my ssn

These are people calling from British Amerrica, so do not pick up thenumber because sprint will charge u 39cents a minute and DO NOT GIVE THEM ANY OF YOUR INFORMATION!!! Luckily, i never picked up for this number, so don't didn't get charged, but from what I heard from others that they got charge.

I answered, Said it was Sprint.  Advised me my account was stolen.  People are buying phones using my account.

Claimed to be from Sprint, but my phone listed the call as coming from British Columbia, no company name listed.  Wanted my address and PIN number (!) -- refused and called Sprint directly -- they don't know anything about this number, and said I was right to refuse to give info.  It's definitely suspicious

I have had four calls from them.  Good thing I did not answer them.  I had already called nextel directly.
