Lack of communication from Stratum

I am so disappointed at the lack of communication I have received from Stratum. I have tried getting into contact with them since 11 December 2024 with regards to cancelling my policy. I have emailed, called and even texted on their WhatsApp line. I was told that it would take 31 days for the cancellation request to be processed, however, I haven’t received any telephonic correspondence (this is necessary to confirm cancellation). They haven’t been replying to my multiple emails. I just got debited again today when in actual fact its way past the 31 days and my last debit should have been in December. This is so frustrating because I am paying for something I no longer want!
