Incorrectly debited for 2 years

I have been "canceling " my mobile insurance since 2019! I have over 2 years of ********** debits from Edgars

This was done in store and confirmed, reason for cancelation I had to wait 3-4 months for my previous insurance claim to payout because the didn't have stock (I have taken my insurance to Vodacom as a result - I have proof)

I further have proof of emails querying this charge as far back as 04/2019 yes still getting debited!!

I utterly refuse to pay my current account and what does Edgars go and do but ruin my credit score

I have been on the line for 2 hours today to get resolved, 3x agents dropped the call on me!!!
