The same happened to me last week. Very vulgar! I couldn't believe what I was hearing. Thought I was just catching him on a particularly bad day but I guess it's just common practice for these people. Scum!
This is just one of MANY calls I have received to my cell phone lately. Just started about a month ago, and I've had about 15-20 calls from unknown numbers, that never leave a message...WTF??
Picked up call, automated message about credit card interest rates. Threatens that this is last attempt to contact or else... Just a scare tactic for you to talk to a telemarketer
