Online Shopping unreliable

Order Number: o ********** 16 I have placed an order on the 05 Sep 2017 during which time there was a promotion on online orders, less 30% on children's basic underwear etc.

On Sat, 09 Sep 2017 I received a call from Woolworths regarding a substitution. I agreed to the substitution of the underwear style, bikini vs briefs. Looking at my transaction history, I can see that the 30 % discount was not app**** to the substitution and the full amount was charged and deducted from my account.

There is another major problem. The size underwear I ordered is 5 years, the size underwear received is 8 year old. The packaging shows 5 years.

Again, I am getting fed up with all that has gone wrong using the online ordering facility. The fault was logged on 12 Sep and I am still waiting for my refund and correction to the order.
