Woolworths review: Staff member

I have shopped at Woolworths Mernda store for 6 years now
The staff have always been fantastic except 1 member today.
Taylah her name was.
She was called over to help me at the self checkout.
My shopping came to $54.30
I put in $4.30 and a $50 note
But the computer still said I owe $3
So I asked her if she could get out the coins I put in as I counted them out as I put them in and know I'd put the whole lot in.
She said, no you didn't you still need $3
I said yes it says that but the girl here another staff member just watched me redo it, put another $3 even though I already had and it is still saying I owe $3 again.
She insisted I hadn't and myself and the staff were wrong.
I said I've already put more than I owe I'm not putting anymore in can you please just check it.
She said "I really don't care this is last day so just go"
I was horrified.
Not only had I put the $54.30 I did owe in but also another $3 in front of a staff member.
When I told her this is ridiculous, you can't just brush me off and tell me to go,
I have money in there and need my shopping she said Well take your shopping I don't care this my last day but I can't give you a receipt because it's not paid in full.
We both began raising our voices she pressed cancel transaction took my cash from the checkout and walked away.
I said to the other staff member what am I supposed to do know, she said I seen you pay, just take your shopping and go.
So I did, but I am now at of pocket, plus I can only assume that Taylor the supervisor took the money I did put in the machine.
I scanned my rewards card got $10 off it said but because she canceled my transaction I don't believe that went through so I'm actually out $13 now and an extremely bad experience at Woolworths.
I was so embarrassed
I live in the area, know people and was made to look ridiculous in the store.
It may be her last day, but you are still paying her to provide customer service, which she clearly did not do.
Very unhappy customer.

My reward card, so you can check if my transaction went through [protected]
I hope I can at least get my $13 back I understand the staff member is leaving so no action can be taken there.
