My experience with Harry Cotter's office has not been positive. I notified the office over a year ago that my divorece was final. They continued to mistakenly send emails/bills to my ex husband with out my knowledge. They apologized repeatedly, and reassured me this would not happen again. It happened over and over until I discontinued all insurance policies on 9/19/15. On 10/19/15 Allstate charged my account 119.56. I was informed by their office the charge was for my exhusbands auto insurance.
