Disgusting Service

I app**** for a credit card in October was approved straight away from blue bean and given a limit of R50000.00. I used the card for the first time last week which was an experience on its own being declined and told my card was block for ***** when i had never used it before. Then on the 08/12/2015 i get a sms stating that due to a bad account my credit limit has been reduced. I have been phoning daily to follow up why this is and what account but no one can give me answer all my accounts are up to date. currently I have been on hold for 20min waiting to speak to a team leader who is busy. I have been waiting for 2 days for a team leader to call me back. this has not happened. i have been transferred to every department possible and magically there is never a team leader or manager available. I am a call centre manager and I would love to go work there i will never have to deal with clients it seems. I WANT ANSWERS
