Shocking empty promises from Woolworths

Woolworhts recently called me to up my credit limit, oncw i took the time to go through my personal details with them and confirm all information, i was told that my R500 voucher will be loaded on my Woolworths app on the 2nd July 2025. On that date when i called their customer servides department, they said that there is a problem with the app and i must try again within a week. Come this week, when i tried checked the app again, no voucher. Called customer services again and they said that there's a problem with their app and to remove and re-instal the app again in 3 days and my voucher will reflect online. Went to the Woolworths store in Ballito Junction yesterday the 19th July and their poor customer services lady checked my app with me, uninstalled, reinstalled and no voucher. She thencalled their customer services department who made her uninstall and reinstall the app on my phone again and no voucher. Mind you we are calling their customer support line from the store itself. The agent says to me that they will not escalate to their IT dept but lets try uninstalling ans reinstalling my app for the 10th time. Mid checks the line goes dead and the agent does not even call me back on my cell, even though she had all my details as i had to do a security check before she could assist me. I am really shocked and surprised by Woolworths attitude in the fault on their app and their empty promises.
