Dell refuses to honour active Premium Support contract after deleting my invoice (their policy)

I purchased an Inspiron 16 Plus 7620 laptop on 11 February 2023 (Dell Purchase ID: 2009483519681, total $1,642.40 USD) with Premium Support. Dell’s own support portal still clearly shows Service Tag BCK8GS3 with Premium Support active until 16 February 2027. However, because their system automatically deletes invoices older than 2 years, support is now refusing to assist me. They are dismissing my original order confirmation screenshots as “not invoices” and sending me in circles. I have paid for a multi-year service agreement that is still showing as active on their website, yet they will not honour it. This is completely unacceptable and a blatant breach of the Consumer Protection Act. Dell South Africa — fix this or at least stop pretending you stand behind your warranties.
