WOOLWORTHS IS *******

I have a credit card with Woolworths, and every month I see that small amounts for every transactions for each that was done are being deducted for taking something over 12 months,and i stlll pay a monthly instalment as welI. I pay my instalment every month on time and then those small amounts still get deducted as well. I was not informed when taking out this credit card at Woolworths that there will be extra charges as well. This amounts does not even appear on the Woolworths app for that matter, that is how clever they are. If I had known this is the case I would never ever take out a credit card with them. When calling to the credit card department they could not even give me a straight answer. Terrible service from them and a *******.
