Woolworths unable to resolve loyalty programme issues and fails to communicate with customers

The loyalty programme of Woolworths credit card is not operative after a change over to a new system in April 2025. Customers cannot access their vouchers and their is no communication to affected customers. I have been told numerous times at the store that the system will be fixed next week and when you enquire via an email or phone I am told someone of IT will call me as they are working on the system. The issue remains unresolved after 4 months and nobody from the IT system contacted me to date. If you enquire online or at the store you are told to download the new app and it will work. After explaining that it does not work you are told that the loyalty programme is placed on hold. Why are they not upfront when you enquire about the difficulties of accessing your vouchers.
