bully tactics by ABSA

Masego of ABSA called me yesterday. She wanted to know whether I purchased pre-paid electricity. I confirmed it. Then she wanted to confirm personal information. I explained to her that she is now asking me to do what ABSA and other banks advice us NOT TO DO. She said that she will block my internet access! I informed her that if she did that, I would most surely report her to ABSA's CEO and write this report. She then said I must speak to her supervisor, one Julia. I explained this to Julia. This morning the ABSA bank account is blocked! It is a public holdiday and I will not be able to pay my employees, who rely on me for their salary - this amid COVID-19. Much as I understand that ABSA try to prevent *****, it is my view that ABSA has erred and that the actions of Masego and Julia were ******* and probably unconstitutional. ABSA advises clients not to respond to requests for information over the phone, yet they contact account holders over the phone!. ABSA has not put my interest first and has not notified me that they have indeed blocked access. They just went ahead and did it. I view this as bully tactics and I will engage the bank ombudsman also on this matter.
