Unprofessional service

I called WFS on the 01/09/2015 requesting a credit limit increase of which I was approved for. I have sent an email with my payslips requesting that my silver credit card be converted to a gold due to the limit increase approved. I waited 17 days for a response and none was given, I then escalated this to the ceo and only then I received feedback. my card was converted but my limit was not increased.I picked up my new card with no limit increased.i sent an email as I was disgusted by the service of WFS.My limit was then declined and Tina said to me that she would go back to the first call and revert. I gave her clear instructions not to downgrade my card without my consent. She failed to comply with my request. I sent an email requesting that my new gold card be sent to the Clearwater branch as this has caused me a great inconvenience. please can someone senior respond or assist with my requests.
