So I've been insured with this company for 3yrs and they are by far the worst insurance company! I pay 200 a month for full coverage on both my vehicles. Recently I had an accident that involved a deer and turned in a claim for the damage! Not only did this company charge me my deductible which is understandable but they charged me another 500 betterment fee for the parts on my vehicle! I had to come out of my own pocket a 1000 dollars on repairs for a 1500 dollar repair!! Why I have full coverage and had to pay 500 dollar fee for parts is ridiculous! They said it's due to parts being worn out over time and by mileage but it's bullshit to me when my vehicle had no issues before the accident and they can charge me that fee!!! I highly recommend not using this insurance company as I am dropping them after this fiasco!!
