DIALDIRECT evasive

I battled from 6 October, to cancel my policy with DIALDIRECT because their rates doubled inexplicably in the space of six months. Eventually, at 10 AM on 24 October I was contacted by a charming lady called Cleo who assured me that my policy was now cancelled. On 29 October R967.04 was taken from my account by DIALDIRECT. On 28 November ANOTHER R967.04 was taken from my account by DIALDIRECT. I queried this at 09:50 on 2 Dec., and received a curt reply from them at 15:10 saying, 'It appears that your policy has not been cancelled'. So I have been paying for two policies, one reasonable and the other not, since 24 October.
