Standard bank building insurance

Had a almost 35% increase in premiums with building insurance, no calls just 1 email, I didn't know until I saw a debit review from my banking app, tried to call standard bank almost 6 times waited 45min to n hour to get hold of someone just to put you through to other people, and never get a straight answer, they eventually offered me a plan with hollard, the person who called me was on leave for the last week, I have left 3 messages to call me and nothing 2 weeks later I'm still awaiting some reply, disappointing service
