Only new business calls are answered ...

I had A A vehicle insurance for a very long time. I cancelled my policy and emailed my notice of cancellations a few times. This month they took another premium via debit order. They only take new business calls and forget about their current clients. I am so glad I cancelled my policy as service is deteriorating hourly. So, so sad compared to service levels 20 years ago... Kindly refund my money urgently.
