Credit Card Cancellation is a nightmare

I attempted to increase the limit on my Gold Credit Card, and instead I was upgraded to a Premier Credit Card. I did not select this option! So now I want to cancel the Premier card and only increase the limit on my Gold Card.<br> <br> Went into the Bank, who told me to phone Credit Card Services which i did from the Bank, only to be transferred to 2 different departments before reaching the final person i spoke to. This person told me they do not do cancellations, I need to email [Email Removed] with my problem and my details and they would give me a call and cancel my card. I have done that, and I am still waiting to be contacted.<br> <br> Why is it such a mission to cancel a card that I did not apply for in the first place? I would like this to be escalated to the relevant department please, and have my card cancelled while increasing the limit on my Gold card.
