Legal Question in Business Law in Illinois

If you were not properly charged they should credit you. Otherwise of course you can sue them but they will defend their charges based on the lengthy contract terms and conditions of your service plan. Your lawsuit would have to attach a copy of the contract, then the billings that show they are improper charges. If you can do that you may have a chance. It could be time consuming and costly, and in most service plans you could be knocked out of court and wind up having to arbitrate the charges, very possibly in a location far from your home.
