Worst service in History Makes me sick

I phoned last year to increase my home contents insurance was told i will get a phone call back and emails been a year since, called today again, was told i will be called back just now its been 5 hours no call back again.

This is ridiculous think i will be cancelling the service and go to an insurance company that actually wants to have me as a client insane, plus you wait on the line for 20+ minutes then then get transferred 5 times, and be rude to 2 of those times its just insane how do you still exist as a company treating your long paying customers like this sies man
