No fedback after 2 emails

I have send 2 emails requesting information on my policy, no response. My emails are delivered. From 1 Jan 2018, vehicle values reduce and i want to know what my new debit order will be for my policy, but clearly the customer service is not interested in assisting or answering my mails. Not impressed. Surely the value and my payment should reduce when a new year start. I requested feedback per email ONLY. Do not phone.
