Left a msg on my cell; said he was sorry for taking so long to get back with me, left his name "Rick Morgan" but said nothing about the company he represented. Offered interest rates of ~1% and said "I see here you are only making the minimum payments, so . . . "
I haven't called anyone about this, so I feel relatively confident it is phishing. No details, no reference to who he talked to, etc. Left phone # 1-800-676-9314. Google that number to get the rest of the story.
