unfair warranty claim rejection and unauthorized debit

I am writing to lodge a complaint against InsureAfrica Underwriting managers,regarding a highly dissappointing and ********* experience i have had with their car warranty service. I took out a warranty for my vehicle through InsureAfrica, under the impression that i was fully covered in the event of a mechanical issue. However, when i submitted a claim, i was told that my claim was rejected because i did not "qualify for the cover" i was claiming for. Instead,i was told i was only covered for something far more limited. Something i was never told at the time i took out the policy. Due to this lack of transparency and what's consider to be a misleading conduct, i chose to cancel the warranty. InsureAfrica confirmed in writing that the contract had been cancelled and that no furtherbdebits would be implemented.

To my shock, the very next month, my account was debited again by InsureAfrica. Immediately, i contacted them to request a refund, but my calls were abruptly disconnected, and i have not received a response to the email i sent them shortly thereafter.

This is unacceptable, i feel deceived and financially exploited. I demand and immediate refund of the unauthorized debit and a written confirmation that my details have been removed from their billing system.
