Credit card declined and being charged when I have money on it

I Being charged when the credit card declined, when I have money, this is no longer funny, I cannot be humiliated all the time I am using this Credit card, and when I complain here u tell me that I must call your call centre no, where the consultants drops the call immediately when rhey hear that I am complaining about the fees that I am charged wn my card is declining, for the last time resolve this issue and refund me the money that I have been charged from last year,

If this issue is not resolved within 10 days, I am going to closes this dam credit card.
