Who called from 3607955688

Just received a call but I didn't answer.  They left no message

Just received a call, I called it back but I got a busy signal.

I answer and said hello a few times and didn't get a response called back and nothing...

CREDIT CARD SCAM. Ignore them.  I answered the call on my cell phone (which is on a no call list).  They could not give me a card name.  They claimed to be working for my credit card company but could not tell me which company.  I hung up.
