Complaint Review: Allstate Insurance

I was hit by a driver that did not have enough insurance to cover my wheelchair repair and doctor and hospital bills. I have had Allstate Insurance for many years and what is called "under insured motorest coverage". I sent a claim to Allstate your in good??? hands, and was told that the bills were not from this accident. All the bills dated the day of the accident from hospital and doctors. My wheelchair, yes that's right, I was in my wheelchair when hit, were from the accident. I was told that they would not cover any of it.
I asked them what under insured motorest was about if not to cover bills unpaied by his insurance. NO ANSWER??? WOW are you in good hands ????? You better guess again. It's good for them to take your money but not give you anything for it nothing. Watch out!
