it's a hang up call. when i call it back it asks me if i want to speak to a representative or put my number on the do not call list. i have tried speaking with a rep. and putting my number on the do not call list. when i try to speak with rep it says all agents are busy. when i select the do not call option, they call back within the hour. have had 7 calls from this number in last 12 hours.
