Lies, lies and continuos bad service

I have received the worst service from FN b, I app**** for a credit card and followed all the necessary procedures, next thing when delivery is done they bring me two cards, I fmgl to the bank and advise of this so I can activate the relevant card but I am told that R ********** is pending on my account so the card is blocked and someone might have put ***** on my account, I really do not understand how this is possible when my credit limit for the inactive card is less than R20 000 I however get advised I will be called by close of business, next thing no one says a word, I contact the ***** department to find out, I'm told the guy with Case has went home and I shouldn't worry about the R400 000 as it is transactional limits, I will get a call the next day. I wait and wait and when I call I'm told Monday will be the day to call. A team leader speaks to me and lies about adoptung my case and making sure I'm called. No one calls me on Monday, I call in a nd hold on for over 30 min being taken from pillar to post, net thing a lady calls me and tells me she's handling my Cas le but was unsure of my banking details, this is a lie as I submitted my banking statements when I app**** for the card. She tells me not to worry of the R400 000 that it is just limits and she will call before close of business to unblock card.. Nothing happens.... As clients we ask for credit for different reasons that are emergency and I can always be calling in like this morning where no one answered for over 30 minuites, can I get urgent feedback so I can apply elswer for credit if FN b is not willing to help and assist in credit that I will be paying back with relevant interests? I'm sitting here worried about my name being dragged in ***** when all is just a lie? What is going on??
