Frequently Asked Questions:
Q: How could someone use my card if I have my card?
A: It is not uncommon for fraudsters to steal card information from a merchant or an ATM without anyone’s immediate knowledge. At Westerra we strive to provide the best security possible for our members. It is important that we block your card immediately if you suspect any possible fraudulent charges on your card.
Q: I mistakenly left my card at a merchant, but went and got it back. Why do you need to give me a new card and new number?
A: If your card is out of your possession there is a chance someone may have copied your information. To be perfectly safe in these situations, we will give you a new card with a new card number.
