Service And Rebates ?

First thing I want to thank you for providing excellant service, in everyway.  In 2012, I broke and or lost two phones, this is #3. The first one I bought had a $50.00 rebate. sales person told me it comes automatic since it is special introduction. A week later I broke it,so i bought  the same phone again, same deal, $50.00 rebate. Eight months later I lost that phone, so I buy a better phone. also with a $50.00 rebate. this last phone I had to mail in the receipt in order to get my rebate, and I did. Now here we are 2013  New Year,  and I have not received any of my rebates  please help mr michael melendez
