Hate getting threats from ABSA

I would like to lay a FORMAL complaint regarding the service I have been receiving from ABSA this year. I lost my job in February 2019 due to cost reductions in the company. I was overseas for the past 7 years. My previous Private Bankers, Cleo Mbatha and Renette Potgieter were both informed in advance about my job loss. They have been moved to ABSA Fourways. My Cheque Account has been in a negative balance since I lost my job in February 2019. I am searching everyday for a new job, but it is not easy. I am being harassed by ABSA everyday telling me that they will take legal action against me for not pay off the R8770 negative balance on my account. Does ABSA think that I want a bad name or that I am not paying my account on purpose ? What type of idiot does ABSA think I am ? As a Private Bank client, I am totally disgusted by the service I am receiving and the threats from ABSA. If I had the money, I would definitely pay off the amount owing. Losing your job is already very stressful for any person to go through. I would not wish this experience on my worst enemy. ABSA does not understand my situation and is just adding to my existing stress of being UNEMPLOYED. I hope that when one of you are faced with this situation, you will understand the plight of 6.8 million South Africans who are currently unemployed.
