Cancelled my policy

Been a client for years. Outsurance cancelled my business cover. I sent the required documents through to have the policy reinstated. Been on the telephone for 2 weeks now with Outsurance & still my business remains exposed because no one is getting back to me. Delt with Marius, who surveyed the premises. Left several messages on the system & still Marius is not getting back to me. Poor poor poor customer service!
