It can happen if you get a CSR who happens to be more empathetic. That said, some issuers are easier than others. Barclay's and Chase pretty much record and notate each call, so if you hang up and try again, they are going to notice you already spoke with someone about it. Not to say repeat attempts don't work with say, Barclay's, but it's not as frequent, simply because they can see you've already called.
