Dissapointing Service!!!!!

I have paid up all African bank accounts, several times I went to the branch to apply for a loan and I get rejected because on their system it still shows areas on the credit card. Called several times to get this sorted out sent emails, sent paid up letter this was not sorted out to date. The is no consultant who is competent enough to assist, callcenter or in branches. This is so disappointing. Can I be contacted by someone who is competent
