Tried to register online,to upgrade my policy, their registration site would not accept my policy number or the renewal policy number, so i phoned them. The person who answered tried to register my details but had the same results as i did she the asked her college for advice a few minuets later she said that i had to purchase the renewal policy so that i could register it. NOT BEING STUPID i asked if i PURCHASED the policy with the same number and registered it would it work ?. she replied yes, Again NOT BEING STUPID i said i already have a policy with a number with castle why dose that not register ? her reply, i don't know. QUESTION ? how do you know the renewal policy number will work. reply i don't.
