Helpless

I have been a regular client with African bank and payment were always up to date, recently the company that I work for has gone through a financial crisis, from this it has set me back financially as my salary comes on different dates, resulting to this I have been charged a lot of penalties. for this reason I have approached African bank to explain my situation as I want to pay however I just want my monthly debit order to come down a little, I received a call from an extremely rude person telling me about my account being in arrears etc, after explaining my situation again she is constantly telling me that she wants to see proof that I am getting my same salary, African bank is not understanding and the more we try to make payment we instead get shot down by rude people, I was threatened to say if I don't submit 6 months banks , pay slips and affidavit from the police station in 2 days time, she is going to black list me. if this is the case, by all means do what you want. because the more I am explaining my situation the more I am being shot down for not paying my account. all I wanted was for African bank to bring my installments down until I get back onto my feet as this moment I cannot afford to pay the full amount on my loans.
