Woolworths call centre agent tampered with my affordability so I don’t qualify for store card increase

I got a call from a call centre a agent named Cece Kenana or Sisikenana from Woolworths that called regarding my store card credit increment, literally after she confirmed that she was talking to the right client, asking me to confirm my details, the call disconnected and I thought she would call back which she didn’t. Today, 19/07/2023 I got a call from Woolworths and I’m thinking it was a call back to finish off the store card credit increment, literally at the end of the call the agent that phoned me today says my credit card application is approved, I then told him that I don’t want a credit card and that I thought this was a continuation of the call that was disconnected a day before. He then said no and I declined the credit card, he then said he will get someone to call me so we can finish off the store card credit increment.

Literally not even 20 minutes after that, I get a call from ab agent calling from Woolworths and they were very keen to assist me with the store card increment, but before we could proceed he notices that Sisikenana finished through the application even after our call had cut us off.

Now what I want to know is how did this Sisikenana or Cece Kenana complete my affordability in my absence when I qualified for a credit card and the store card increment declined, more so when my affordability last updated with the retailer over 5 years ago?

Is this even allowed that Woolworths call centre agents should mess up with our scoring putting on incorrect information there when it is going to negatively affect our ITC scoring in this already declining economy???
