STD Bank, just a bunch of *******

Never in my life have i ever seen anything like this before from a major banking name like i have with Standard Bank. A few yesrs ago i posted a review on Hellopeter regarding Standard Bank that was charging me every month, sometimes even double charges for a cheque accont that had closed months prior to posting the review. I got a response from a branch manager and the next day all the charges where reversed and the account was back on a R0.00 balance. That was roughly 2016/2017. Now a few years have passed and suddenly out of the blue im getting smses NOT phone calls every single day telling me to make payment arrangements to sort out the account. I havent banked with Standard Bank for years now already. So now where on earth does this apparent account come from? Is Standard Bank busy with ***** by activating previously closed accounts and sending it to debt collectors demanding payments? its ridiculous... and they expect a person to trust them with our hard earned money? Unfortunately i no longer have access to my old hellopeter profile as i had to close my old email account due to it being hacked. Also i called STD Bank customer services to enquire about this nonsense and all they tell me is they cant help me as the account has already been refered to the debt collectors. And to top it of i then try to call the debt collectors and it just rings or .the call gets dropped. Its wrong to think of how major a institution like STD Bank can think or do as they please with things like this
