JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

Unsolicited issuance of credit card Maryland

I recently received an unsolicited Amazon.com Rewards Visa Card in the mail issued by Chase Bank VA, NA. The card has moderate to generous reward options. I subsequently received a letter in the mail from Chase ( again unsolicited ) referring to the issued card saying they would need more financial information in order to approve me and that I was to call - with a Reference Number. I am not sure if this is a - - type incident where someone is getting bonuses for issuing cards, a spear fishing style scam or if my ID was compromised but in either case it is concerning. I did call Chase Bank to cancel this card and inform them of my concerns ( not revealing any of my financial data ) but they told me to call back tomorrow to - which on reverse lookup is listed as an unlisted mobile number - not calling it.
