Credit Limit increase - No feedback on status of application

I app**** for Credit Limit increase on my premier card in June 2017. Information needed was being requested in drips and drags all the time after i give the department a call to find out how far my application is. Fast forward to October, i sent through "all" the information requested to the email address provided but still no feedback was received. I have been calling almost everyday from last week Monday to check how far my application was and was told a priority has been set on my application and i will get a call from a consultant which never happened. I was advised that all is in order and the application has been approved. Today i then called to investigate why the application is on hold and no one seems to be giving me a direct answer only to be to be told that i need to visit the branch and fill in a declaration form. This i did and after all the effort only to be told that i do not qualify for the credit limit because my work permit is left with less than 6 months. I had asked in the beginning if this will not have an impact on the application of the limit since i am permanently employed. I am really frustrated that only after i probe for information do i get feedback and after losing so much money from calling in the whole time to get information. Just as a note i have app**** to renew my permit and i have documents to prove this
