Lack of customer-care service

I added my family members to my active membership in June, and it has been over 2 months and I didn't receive copies from my Discovery 'physical' Card. Despite my telephonic call to Discovery in July (when I did realize that they sent the cards to an old address that is no longer valid since 2018 - As I am keeping all my residential addresses update to date regularly), still didn't receive my cards. Some local healthcare facilities do insist on physical cards to make copies (they don't like digital cards or giving card numbers??). May I have my cards please esp in case of ER. Prof. Irhuma
