Your bank is disappointing

I've been trying to deactivate my credit card since last Friday; your service is absolutely unsatisfactory. Every time I phoned, a different consultant answered the phone, and they all offered me any and all justifications. I spoke with Tintswalo Mhlanga once more this morning, and she told me that my credit card cannot be closed off since there are daily charges to it and she is unable to identify any consultants who have worked on my profile. How ? in a bank? You're telling me that unidentified Standard Bank employees worked on my account yet left no trail? I'm always instructed to wait until the next day when I call the bank. This is *********.
