fnb premier banking call center or what is it

What the purpose of having people in a premier banking call centre who cant give you a simple breakdown of your account, i paid R5900 into my overdraft and amount was decucted twice, according to agent it was not and i asked for proof of that which she gave me long stories but not the answer to the question, i asked to speak to manager Khamogelo Dube and i was refused , is it really premier banking???or just a normal call centre???<br> ***<br> to top it off my call was cut off twice after the verification process and im afraid something ********** will be done on my account, what surety can fnb give me that after veryfying my account and phone been cut off that my information and access to my account is safe.<br> <br>
