I answered but it took too long for the robot to switch to human so I hung up.

Sounded like a call Center in the background, very noisy, took ages for person with forge in accent to speak

Claimed to be Visa calling to lower my interest rate because I am such a good customer and always pay my bill on time and always pay the entire amount owing and had never been charged an interest fee. I asked why Visa wanted to lower if I don't need it then offered to give me 1000 points on my account if I would.
I then asked him to identify the bank that issued my card and he hung up.
Idiot!!

When I answered - a recorded voice said good-bye

Same as Teresa - I answer and they hang up.
