DISGUSTING CUSTOMER SERVICE

I have had an appalling service from African bank. I called in requesting for a settlement discount on two account that I have had with them for some years. The discount they offered me was too low and I asked them if they could reconsider. I was told to send an email to *** and the turn around time for the response would be up to 72 hours. This was on the 11th November and I have the mails to prove this. The 72 hours passed and no one had made contact with me, I called again and explained this situation, spoke to Margaret who put me on hold for 25 minutes until the call cut. I called right back and the consultant I spoke to said she escalated the matter and a supervisor would call me and no one has made contact with me since. How do I settle these accounts if none of them call me back, they want me to continue paying this account in small installments. The only time they will contact you is if you miss an installment. I have paid these accounts over a couple of years already and I know that they do give bigger settlement discounts. I want to clear my credit profile and they are standing in my way of doing so, all they want is to keep taking my money and the debt is standing at one place, it has been years. Every time I call I need to tell the store to a new consultant each time and I am kept on hold until the call cuts, then I have to call back and start the story from the beginning. They are the worst credit bank out there, STAY AWAY from them, they do not care about customers. They just want your money. The only way they will contact me is if I return my debit order, then they will call me non stop.
