Write down the product number and go to remingtons site and enter it in the system then search. see if the store location and date/ time is on there (it may not be) if it is then print it and take it to that same store and insist on a back log they can print that out for you. if the site does not offer all that info then call or email a request explaining the issue and a replacement can be shipped or refund of the money either thru them or they will send the info or give you the info to give to cvs & they refund the purchase or replace it.
