Unauthorized debits, no refund to date

I phoned on the 14th of December 2018 and spoke to Sifiso to cancel my policy and request a refund, I filled in the relevant documents and received confirmation via sms that the policy was cancelled. I phoned on Friday, 11 January 2018 and spoke to a consultant by the name of Puleng, enquiring about the refund and no response was given to me as to why the delay had occurred. It is the 14th of January 2019 and I have still not received my refund, furthermore, Assupol continues to debit the premium from my payslip for January and February of 2019!

This is now theft and unauthorized debit because cancellation of policy was cancelled and I have proof thereof. I want my refund and for Assupol to leave my salary alone or else further action will be taken.
