14 wasted calls per week, 56 wasted calls per month Woolworths wasting money

My wife has an account with Woolworths and used my mobile number to open it then (20+ years ago). In 2022 we changed the contact number on her account to her own mobile number. We did this at the Services counter at Woolworths. It was confirmed as changed. Since November 2023 I have received between 2 and 4 calls per day, every day, with regards to my wife's account. At first, I suggested that their auto dialer system be updated to the newest information on the account. Lots of promises were made, yet I still got phoned. Then I suggested that they leave notes on their interaction screen regarding the correct details. Also offered to listen to what the issue with the account could be, so as to resolve and stop the incessant calling. The response was that details pertaining to the call and account was private (sic). Eventually I had to call the department directly with the aim of lodging a complaint and getting the matter sorted. No joy, call got "dropped". I'm not ok with 28 fruitless calls per week and definitely not ok with empty promises and shoddy admin from a recognized big name retailer. Hello Peter is my last resort
