Took up the special offer of $3.87, received goods twice and charged $4.51 on the23rd & 26th August, then charged $87.47 on the 1st Sept & again on the 2nd Sept. Then on the 30th Sept charged $93.67 twice and $2.95 twice on the same day.
I have now made an official complaint with my credit card and also cancelled the card to avoid any further charges.
I am in Australia.
