Tip from 1st for Women: If you've had your car insured with a specific insurer for 3 years or more, you should do a comparative shop-around every 3rd year - insurance companies will automatically increase your premiums annually and when they do this, they do NOT look at your claims record - it's just a standard, across the board increase, which I why I was paying over R1700 p/m for my car.
Had I shopped around regularly, I would've been in a position to negotiate with the insurer I'd been with for 20 years and could have received a better rate from them. I still changed my insurer because I felt that after 20 years, it was A&G's responsibility to contact me and offer me a better rate due to my long standing loyalty instead of lumping me in with the mob - had they made an effort to look after me I probably wouldn't have changed. It was only when I cancelled my policy did they start falling over themselves to retain my business. And I hadn't had a claim for more than 12 years!
