Cancellation request ignored

I called the contact centre same time last month to inform them about my intention to cancel all my value added services. This was as a result of the stinking service I got from the same company. I was sent forms which I completed and sent back same day, and was told that it would take 21 days to process.

The 21 days have come and gone without any feedback or confirmation. I sent a follow-up email last week, and got no response.

What makes me mad now is that they **********ly went in and deducted premiums for the same services that I requested to be cancelled! How exactly do things work here?? Because I informed them well in advance about my intention to cancel??

I want my premiums back, and I want all the necessary refunds paid asap. The 21 days I was told about expired ages ago
