Misleading n poor service

I received an email for a automatic increase for my credit. I filled in the forms and submitted these forms. 2 weeks later I call in to ask about this increase, they requested me to resend. And they can see the automated increase etc. Another 2 weeks and still not increase. I called in they state they will investigate. Another 2 weeks, then the offer is there but I need to do the checks all over again. ***. Don't waste our time. Either give the increase or not.
