bad customer service

I went to african bank requiring a loan,was advised to take a 3rd party settlement loan even though the 3rd party had already been settled,I was assured that the 3rd party will reverse the money into my account,the money was instead reversed back to african bank.I then went to my nearest branch to query whats going to happen regarding repayment installments only to find out there's an extra amount that was charged on the loan,I called customer care ,the consultant logged a query on my behalf someone called me saying they are busy with the query since then I got no feedback.I called the customer care centre four times already but still my query is not resolved,african bank never bothered to get back to me just to let me know what's happening,,every time I call the consultants tells me a different story i'm very dissappointed in them.I really regret doing business with african bank
