Credit card department in shambles

I’ve called their credit card department seven times now and still nobody has been able to help me with a simple issue. All I need is a confirmation letter of a lost credit card, but after seven calls and several escalations still no letter.

My last call I was put on hold for an hour. So unprofessional
