Increase on insurance

We have been with absa idirect for years and have had great service but over a month ago we needed to upgrade the insurance valuation on our boat. Numerous emails have been sent with an official evaluation from a well established boat dealership and have had no response. We have tried calling and to say the operators that answered the call were not interested is a understatement. Even when we were put through to a supervisor NO ONE could help. My question to you is simple....... if something happens to my boat am I covered due to your incompetence???. I am currently looking for alternatives insurance due to this. Surely it can't be that difficult to update and increase the value of a asset. We have all our insurance from household, car, boat and building insurance and im sure with the current state of the economy and country even us small insurers make a difference..... or I should hope atleast. I cant say I hope to hear back from you because if your staff are unable to assist how will you be able to? Kindly let me know if increasing the value of one of my assets is so much of a issue I must ensure by the end of this month I have a insurance company that is willing to look after me.
