Nightmare dealing with Standard bank

I have never experienced such bad customer services in my life like I did with Standard in the last week and to date. Called Standard on the 4th of April to decrease my credit limit on my credit card and to my surprise that was never done instead the lady that was assisting me made my account to be over the limit because the calculations were done incorrectly and as we speak my account is sitting on a negative balance .

I call on a daily basis to get this issue sorted but no one is assisting me , every single time I try and ask for the manager or team leader they are in a meeting but I get calls every hour from the legal team to try and collect money because of their own error on their side . I even went to the branch to get this issue sorted as advised , but their couldn’t help as well . This is already affecting my ITC but no one cares about that . No one ever gets back to you . It’s their mistake and they should ne fixing it
