ZERO loyalty towards customers!!

I have been with outsurance for about 4years now, NEVER have they had any issues with me, no claims, no problems. I was told the day I sign up that when I turn 25 my premium would be lowered as I am a lower risk, infact since I turned 25 my premium has gone up from R976 to R1300 in a space of 3 months, when I phoned to dispute this, I was told that nothing can be done and that is it. After all these years with me not costing them a single cent, absolutely pathetic if you ask me.... THANKS FOR NOTHING OUTSURANCE!!!!
