annoying African bank with stupid phone calls and sms, Remove my number please

African bank please tell your people to stop calling me or sending me stupid sms about other people's account before I start swearing at them over the phone. I have asked them nicely to remove my number every time they call me, I even went to your branch and those annoying people giving stupid excuses to remove my number on your system. I don't owe you anything and I will never use African, for WHAT??? I'm really gatvol of getting sms and phone call, next time they call me again, I will lekker swear at them and I don't care if it will be a female or male person. don't you guys verify people's informations before borrowing them money??? someone gave my number as reference before he works under me it doesn't mean you have to send me his informations and all *** smses... REMOVE MY NUMBER on your system
