DOTSURE - UNRELIABLE

On 21 July I cancelled a policy with effect from 31 August, received no response at all until 23 August by SMS reminding me of a pending deduction 2 days later. I forwarded my cancellation email as a reminder. I received a call the same day explaining that it was too late to stop the transaction from going through, that they will pay back my money in 5 days. They never did. On 3 Sept I sent them my banking details. No response. I want my money back. My cancellation date gave them enough time to organise themselves.
