Gross negligence and shocking service

Crazy bad service. Added a vehicle to an existing policy on the 27th on September fully comprehensive policy was agreed upon and I was asked to send the proof of a tracking device within 7 days. This was uploaded via your spp and via email to the address provided ***. when I phoned to update the reg today, I was advised that I am only covered for fire and theft, as the proof of tracking device was not received. Post investigation the reason for first for women not adding the document provided on the 29th was that you changed your email address to ***. So my policy was downgraded because you cannot manage your internal processes. Shocking..
