Bad service!

I'm highly disappointed in the service I've been receiving. Updated my physical address on the 4th of April, then my premium decreased, which was great. Upon receiving my policy schedule I notice that they changed some information, without my knowledge. Weeks on end been trying to have them rectify this matter, then suddenly my premium increased again when they attended to it. I fought it still until it got back but only to realise that they again inserted information that I had not provided. I am so exhausted as this is daunting! Furthermore, gave a friend's number for the referral campaign, a friend who is in need for an insurance (this was 2 weeks back) made a follow up, they keep on giving stories. The service has gotten pathetic lately!
