Not even shocked

I recently had a sim swop and because of that I couldn't purchase airtime from my bank with their self help options. The pop up notification said I should call 173, which I did. I was told by the consultant to call 808 because my phone is a contract phone(which made sense). The gentleman who \helped"me there said they couldn't assist me because it's not his department and that I should call 173 again because even his supervisors won't know what to do because it's not their department that deals with that . Which I did... I'm guessing you can already see where I'm getting with this. I called 173 and the lady there who wasn't very impressed that I'm taking out my frustrations on her told me that she's transferring the call back to 808. Which she did. The call then got cut. I'm not sure why or how you can put people who don't know what they're doing to be the ones assisting your clients. I'd like help in resolving my situation of not being able to buy airtime from my bank. Thanks """
