Wollworths refusing to divulge costs of using credit card

Wanted to get a credit card from Woolworths App**** and was offered a card Then asked for the costs of using the card i.e. costs for using it in-store, other stores, ATM withdrawal, using overseas, etc. No one either at the store or the call centre could give me the costs. They all said that I must open the credit card account and only then would they give the information about costs Sign up for soething not knowing the costs. Riduculous
