Cancelled Credit card inquiry,

I dont even think you deserve 1 star. I have been battling to cancel my credit card since May 2021. I was contacted by one of your agents in July 2021, they assured me i will receive a refund in 3 days. A whole month have past and i am still waiting. I was on the line with a call centre agent few minutes ago. The 1st thing that ****ed me off in stead of doing the greeting she was laughing. She took her own time before she asked me the verification questions. after i was verified. I explained the query to her she told me the card is cancelled and she asked my refund details. and i was on hold for over 20 mins. then the music stopped and there was just dead silence. I called back 3 times i heard the call was transferred to an agent but it was juts silence. Please i need some one to call me i am sick and tired of dealing with useless staff and lies.
