Clientele is so unresponsive

I took a policy on 8th December 2023 . I canceled this policy on the 18th of January 2024 by sending an email. I received a response from clientele on the 24th asking for confirmation details, ie bank details and date of policy debit. I provided this same day via email on the 24th January at 11h43.

According to clientele the payout for the Decembee premium was R126.35.

They then proceeded to take another amount off on the 27th of January in the amount of R530.

I've been sending them emails and contacted their whatsapp number and to date have not received any response
