Just one ring on my cell phone from this number - CID says Zap, ND (I've never heard of it). I looked up the number online and here. It appears to be yet another credit card scam, according to what others are writing. The one ring thing is a trick to get you to call back so they can steal your phone number and used it to spoof themselves, while trying to scam others in your calling area. Block it and report it.
