No communication from SB as usual

I grew tired of SB insurance's lack of service and sent them notice by e-mail of cancelling my policy on 29 June. I received no response. So I phoned the call centre on the 7th and was given another e-mail address to send the cancellation to. I was assured I'd get feedback. A week later, nothing.<br> <br> As far as I'm concerned my policy was cancelled on the 29th. If SB charges one day more premium, I will sue them for it in the Small Claims Court, no matter how small the amount. I'm tired of their utter inability to perform even the tiniest and simplest task.
