Talksure ignores requests to cancel.

I considered taking out a policy with Talksure in April last year. Just after agreeing to taking the policy, I decided to cancel. I sent emails and phoned them to cancel the policy. It was an Elixi Gap cover policy. Since then they have continued to deduct the premium from my bank account. I have phoned numerous times, but they still deduct. Today I notice that they deducted almost double my premium! I phoned again, but was sent from person to person. When I got through to the last person, the phone went dead. I phoned again, and they said they would get someone to call me back. I am still waiting. This is terrible service. The worst part is that I have been phoned by them repeatedly for new products and repeated my complaint, and still nothing is done!

Please help! I am fed-up.
