Im new here so figured I'd share on of my methods. Call any razor company (gillette is one of the best) tell them the head of the razor bent and the store wont accept it back because of pkssible bodily fluids, tell them the razor is brand new never used. They will ship you a new one. For rechargable razors tell them the charging light co.es on but the razor will not power on, they will ask you to send the razor back but tell them the post office is not allowing it because it has a lithium battery or tell them you used it once before it qhit working and you have hep c. For more expensive razors you will need to buy one to get the numbers off it then return it to the store for refund.
