Once Again they dont deliver

My account number is *** and mobile number +***4. Since January 2014 whilst I was temping trying to obtain a permanent working position Absa offered my an overdraft on a sliding scale which I gladly accepted. I gainfully found permanent work at The Star newspaper in December 2014. I informed Absa about my current status and continued to pay off my overdraft. I recently went in the Brixton branch to apply for an overdraft facility again. This was denied with the bank saying my credit rating has dropped. I find it disgusting that when I was not in permanent work they offered me a loan and overdraft but since being employed permanently it is declined. This bank is all about helping you further into debt when your not working but wont assist you when you are working. It is a bank that will never get a referral from me! I am reducing my credit card limit so as to close this stupid account and move to a bank that is willing to assist a person.
