Dishonorable conduct.

Due to unforseen circumstances I fell in arrears with my African bank loan. I made arrangements with the consultant who phoned me to pay off my loan at a nominated amount. A debit order was set up and the first debit order went through as arranged. When the next months debit order went off it is nearly three times the agreed amount. Due to that i have other debit orders that won't go through. I am really just trying to get back on my feet again but now I feel like I was stabbed in the back.
