No credit card account on system

A little over a month ago, I tried to use my credit card and it was declined. Which I knew was impossible as I knew there were funds and the card wasn't expired. I called the call center and said that the system blocked my account as the type of account was not a standard bank product anymore and I the system blocked my account automatically. Needless to say no correspondence or sms was received regarding the change of my account. When I called the call centre I was told to go into a branch which I did. When at the branch I was told the call centre could have done everything. The branch sorted everything out and ordered a new card. Last week I went into the same branch to collect my card. Well std Bank sent it to a different branch. Today I went to the other branch to collect the card. Only to find out the account (card) doesn't exist on the system and an IT log needs to be issued which can take more than two weeks to clear up. I asked for a manager and complained. I was told I would receive an sms with the reference and they would also call me this afternoon. I have received nothing.
