Threatened by insurer

Wow what a way to upset your day if you get such a call from your insurer.We moved over to Miway in October 2014 hoping to have a good experience in terms of customer service and that we can rely on our insurer to have our best interest at heart.Wow - what an eye opener!Their premiums are very competitive but that is clearly where it stays.Just received a call from Miway just to let us know that we should now be warned to not submit more claims or we are at risk of becoming multi claimants which can result in insurance being cancelled.I work in the short term insurance industry and know the principals.At our company however we are not that reckless with classifying someone as multi claimant.I asked the lady that okay I am warned now - what does she expect me to do?? Must I put up a sticker or board on my car and house begging people to please not collide into our vehicles or ***** from our property? I have insurance to cover me for losses - we live in a crime ridden country and surely how can I be responsible for that! We have had 3 small claims of which only ONE claim was even settled - 2 were not covered.The lady's attitude was also very disappointing/
