Woolworths bad client service from credit card department

Worst service ever, I had my card swiped twice at store because payment didn't go through the 1st time, so I need to have the other amount reversed they can't help me, I called every day since the incident happened was told yesterday I was gonna be called back 8;30 am this morning still no call.

It shows clearly on my app the one amount didn't go through however It was not credited yet. Worse service ever tried calling now again un able to reach them.

Worse credit card to have.
