Received call about lowering my interest rate (9014) 449-1788. I pressed 1. A male with a foreign accent answered. Asking about me wanting to lower my interest rate. I replied that I was just trying to find out who robo-called my cell phone, isn't that illegal? He then asked if I pay my bills on time, sometimes paying more than the minimum. I said none of your business. He then appeared irritated and said he is trying to tell me who he is (he never did). I told him he didn't tell me who he is or what bank this is. He then told me to shut-up and hung up on me. I tired to call-back, but it isn't a valid number.
