Awful service

Terrible service from accounts division. Trying to reapply for a credit application and its been a week(after I was told it will only take 48hrs) that the accounts division has not even responded. When I call customer service, they say the samething all the time, Should get a response by today and nothing happens. Its been escalated but to who, and you cant even call the accounts division. If this is the process just to get the credit application, imagine afterwards.
