Auto & General is extremely disappointing

Since joining Auto & General all we have had was bad service. The sales person who sold the insurance to us Jermaine gave false promises and the company he recommended for the tracker Secure Drive is useless (their contact number keeps disconnecting. They installed the tracker and didn't supply a, installation certificate on time. Now Auto & General downgraded, my Vehicle Insurance to 3rd party, without notifying me and still took the full amount for Fully comprehensive business insurance. I requested a call back and am still waiting as try and get through to them is also a problem. I have emailed with no reply except a auto reply notification
