Renewal code and verification

This is not a complaint as such. I renewed my Kaspersky licence online as I always do. I used US website and renewed my computer and Android protection for 1 year as I always do. I made the online payment in dollars as shown and on 22 December 2020 my bank account reflected a payment of R478.01 to Kaspersky for 2 devices as ordered. I did receive an authorisation number, and wrote it down for my records. Unfortunately I made a copying error, so the code won't activate. ( 1 too many characters).

I have tried without success to contact Kaspersky, whose SA based numbers do not work, and each day they tell me to renew my licence. I now have 3 days left. I have sent them an email in response to the email they sent me, and have had no response. I do not know where to find my code so I can correct it. I have paid for the renewal, come on Kaspersky, I have used your product for years, please resolve my issue!
