Interest query/poor customer service

Good day<br> <br> When will I receive an answer regarding my query???<br> <br> Its been 2 weeks already. I just spent 25 min on the phone to the<br> credit card department and all they tell me is that I they cannot help<br> me and that I must wait 5-7 working days for an answer on my e-mail,<br> so you want to tell me each time I respond on your email I have to<br> wait 5-7 days. That's crazy. It's going to take forever to solve<br> queries this way. The operator told me that nobody can assist me<br> except for the admin department which is only reachable by email and<br> then I have to wait 5-7 days.<br> <br> I've had so many problems with FNB in the past and the only way my<br> problems ever get solved is f I pick up the phone and call you and<br> spend half my day on telephone, because you do not always respond to<br> emails.<br> <br> My previous query was regarding interest payment on my credit card!!<br> <br> I asked for the calculation of how my interest was calculated.<br> <br> I want to see the figures, days, percentages used.<br> <br> I don't want to get an explanation on how interest is calculated and<br> all that stuff. I want to see MY OWN calculation which was used to get<br> to MY last interest charged. I want to see the rates, outstanding<br> balance, etc.
