Bad Customer Service

Insured at Discovery Insure since their inception. Also a Vitality, Life and Card customer. Seriously considering to cancel all my business with Discovery as the client care / service / feedback is simply atrocious. Increased my Insure premium with 17% (!!) without informing me or obtaining my authorisation for increased debit order amount. My vehicles are worth less. When I phoned to query I was placed on hold for over 10 minutes, at which point I ended the call. Phoning back the assistance was non-committing and without any solution.
