Kept calling until I blocked the number

Called and left no messages.

Same here.

Just got a call from them and did not answer. When I called back, I got a "call can not be completed as dialed" message.

pick up and it's a recording saying they'll lower your credit card interest rates BUT I DONT OWN ANY CREDIT CARDS so I wait for the person to come on the phone and ask why I'm getting these calls, 3 in last 5 days, same robot call each time I pick up, and lady says UHH UHH and hangs up on me! If you call back, you get a weird recording claiming their lines are busy. SUCH BS!!!
