Unreliable call center and overall poor service

I tried calling the call center for the most part of yesterday but no one ever picks up. This is so frustrating not being attended to. I have been trying to apply for a cash advance using the self service since yesterday and at the time it seemed as if it was approved as the balanced owed had increased. But it was never paid into my account. This morning when i logged in, to my surprise the cash advance seemed to have been reversed back into my credit. I have tried to apply again and only to be getting a message that said only one cash advance can be performed per day. i am confused now. Please help with this by calling me on *** asap.
