FNB - get clients and then mess them over around

Received and SMS saying that my credit card balance as been reduced so got myself into a branch to sort the issue out but no one could help me so I called the call centre and no one could help me either so a complaint was logged. So I decided to follow up on the complaint spoke to a consultant and was thereafter transferred to a manager not sure her full name but it was Natasha and she told me that its company policy and she cant help me as well and further to that she added \Mr Theaver we reduced the amount to what you can afford""; FNB also promotes you to use your credit card to build ebucks and by reducing the amount this also messes me up but what can we say FNB is the BOSS and can do as they please it actually very sad to know the type of attitude the FNB's carry's out towards their clients;Right now I feel like I was ******* into becoming a FNB client and once I become one they *****ed me over."""
