Harassed to increase my debit

I defaulted on my credit card and then after i increased my debit twice to try clear areas on my account , I have recorded calls where was told to increase my debit so that I can clear my areas and I have been up to date since I pay my credit card weekly without fail, but I am getting calls that my areas are not cleared and I’m being harrassed daily again to increase my debit, I have not even seen my statement. The way African bank harrasses their customers it’s very unfair and not professional.
