Claims to be ANZ Credit cards but I'm not responding in case its a scam.

The text message I received from this number said it was ANZ bank offering to increase my credit card limit. All I had to do is reply yes to the message. I'm not sure if it's legitimate or not. Australian bank have little ethics so it could be legit

It's a bout time the government stepped in and closed the these companies down that are stalking people there are laws in this country the government are breaking the laws are they getting a kickback???? Tony Abbott get serious do your job ? Or we get another prime minister
