Charging policy after I cancelled it

I went complete a cancellation form on 3 March 2018 to cancel a policy on my account as I settled this account.

On 6 March 2018, I was charged for the policy once again which I did not have an issue with as I understand that it has only been 3 days since I cancelled.

Today I was speaking to Zama from their online chat and requesting feedback on my cancellation. I was told that they received it on 8 March 2018 and it will only be actioned on 8 April which means I will be charged once again for the policy as their SME is 6th.

I refuse to pay the policy again as I have give Mr Price enough time to action my request.

Please ensure that this policy is cancelled with immediate effect. If not, the charges (policy, monthly account fee and interest) on the account will need to be reversed.
