HSBC Canceled My Credit Card Without Proper Notice or a Clear Explanation

My HSBC credit card was canceled even though there was no serious issue. The explanation given for the cancellation was not satisfactory. I was not notified in advance, and I only found out when I tried to make a transaction and it was declined. This sudden cancellation caused inconvenience in both my personal and professional life. When I contacted customer service, I couldn’t get a clear answer or proper support. Discriminating against customers is a violation of human rights. As long as I pay my credit card regularly, the bank’s attitude is completely unacceptable. It makes me question the trustworthiness of HSBC and whether I should continue banking with them.
