Declined foreign T457 on my account

Since the day I got paid, I have been getting declined foreign T457 transactions on my account. I have no idea what this is but it needs to be sorted asap! I have never been so furious in my life!! There are 9 in total SO FAR!

At this rate, I will keep incurring charges for something I don’t even know.

If I will keep experiencing unknown charges on my account for unexplained reasons, I am better off with a different bank. You guys have lost your credibility!

Please sort this out
