limit increase approved but no funds in my account

I'm not pleased by the service I've received. On the 16th I called through and requested a limit increase which was approved but when I tried to transact the approved amount didn't come through. I tried to do it on the website but got a decline result. Called through spoke to Eva who confirmed that the limit increased was approved and the available amount. The following day I called through and spoke to kea as the amount wasn't in. He assured me that the limit was increased as u could see it on the system ...including the previous transactions. Now on Saturday I returned to the branch as I never received a courtesy call that kea promised me. Spoke to Caroline who advised me that the limit was declined. She transferred my call to her superior Fibi who advised me that there was no history of my limit being increased. Which I found very strange and made me sound like a ****. I asked for her email address in order to forward her the recordings. She insisted that she'll send me a Blank email to date NOTHING. such treatment has left me beyond shocked . This has been the worse experience ever and to be advised that I should go to the branch was even worse. ..loyalty is clearly not recog
