Stop Harassing me

MBD have been tasked by Standard Bank to Harrass me 5 days a week 5 to 10 times a day. I refuse to speak to them and wish for them to stop. If I must repeat myself to them again, I am very tempted to take them and Standard Bank on for the continued deterioration of my mental state. Its company's like this that cause ordinary unemployed citizens to commit ****** or suicide. I want them to stop calling and black list me. Unemployment is high at the moment and jobs don't grow on trees.
