Appalled, disappointed, angry and frustrated

I am extremely upset and appalled by the treatment I have received from this bank. I was cut off from my account with no warning or no explanation from the bank today. I have not done any ******** activity nor have I had any unusual traffic on my account. I called the service center, and I could not be given any helpful information from the bank except go to the branch. I visit the ABSA branch more than my own relatives. Because of this I was unable to pay for my medications from the GP I had visited. So I must return home still bleeding from a menstruation cycle that has been going on for 2 weeks non-stop. Only today did I have enough money to buy the pills to pay for the medication to make it stop and ABSA took that away from me. Now I must go to a branch where I have no assurance if my account will be activated again. I literally feel like I am being held hostage by my own bank.
