Unsuccessful Credit Limit Increase Requests and Cash Advance Issues with Yapı Kredi Bank

I've tried a bunch of times to ask for a higher credit limit on my Yapı Kredi Bank credit card, but they keep saying no. No matter how hard I try to show that I'm good with my credit card and really need a higher limit, they keep saying no. but why?  I also went ahead and applied for a bump in my credit limit and asked for a more flexible account limit. yet again, my request got rejected too, so now I'm stuck with limited options to handle my finances properly.even worse, I've noticed that the cash advance thingy on my credit card has been all halted, which is another stone on the road. what are you guys trying to do??  can you please look into these things and get them sorted out ASAP?  I think someone needs to handle my credit limit increase requests and the cash advance problem properly.
