Terrible Service

I have a ***** query regarding my credit card that has been open since the 26th April 2022. I have been promised my case will be finalized within 7 - 9 days. I was then informed that it would only be done by the 9th of May. Nothing happened so on the 10th of May I tried to talk to a person in the ***** department and got put on hold for 4 hours eventually being cut-off by someone in ***** department. It is impossible to talk to someone to get feedback and all customers get is a tacky response
