Account debited in Jan even though policy was cancelled in mid December

Good day,

I called the call centre on 14 Dec requesting a termination of the policy effective 15 Dec – check your call recordings for proof of the call. I was transferred to someone from your retentions team who eventually confirmed that the policy would be terminated as per my request – I was expecting a refund for the remainder of the month which was approximately 15 days

As of today the policy has not been cancelled and I now have been debited for another month. Kindly rectify and refund me ASAP!

As of today - 04 Jan 2020, I have called the called the call centre 3 times this morning and no member from the retentions team is available to take my call to address my complaint
