This # called my mobile phone -- didn't leave a voicemail.  I give out my cell number to very few people, figure it was a telemarketer of some sort.

I just attempted to contact the number back and got a disconnected recording.  The people calling are using spoof numbers and blocking inbound calls,  Now thats a company I really want to trust! NOT!!!!!!

Just got a call.  Called it back and its disconnected.  I hate this BS

Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.

Cardholder Services calling my cell phone.  Surly there is something that can be done.
