******* will not stop *****ing

I originally started donating R20 per month to their cause, because I believed in what they are doing for this country, yet I have been unemployed for almost 3 years now, & they still keep on trying to deduct this money from my bank account every month, even though I informed them quite a while ago, that I am unemployed & that I couldn't donate to their cause anymore. My account is currently in the red, by over R200, because they refuse to listen, they just carry on deducting invisible funds. I am way past fed up with them now.
