False information, forced change, no feedback

Complaint numbers *** / *** / *** / *** have reference. I was promised an upgrade (I did not ask for it) on my credit card with no costs to me. Interest rate and monthly fee increased without my knowledge or consent. I responded on initial SMS by refusing offer. Current card cancelled while I specifically indicated that I will not collect the upgraded card while rate and fee were wrong. No feedback received on any of my complaints logged via phone or at [Email Removed] Cannot call to complain as I no longer have a valid card with a valid pin. Please advise if you wish me to cancel my account after 36 years as that seems to be my only solution. I am listing my latest complaint date and time below. However, this saga has been dragging on since NOVEMBER 2014 when I was first approached about an upgrade. Horrible, horrible, horrible non existent service!
