Query: customer service/warranty

Received Plat 5000 as gift. Kabob rods missing. Sent letter and warranty card to Ronco as stated by Cust Svs. They lost card/denied ever receiving, will not honor warranty to send missing 8 kabob rods at their expense, told me to return rotis. to store; store will not honor without sales slip for exchange. I will not ask my bosses wife for receipt. First time a Co. did not honor a warranty after 5 attempts to contact and resolve. Am taking back and going to try for credit and will use on any other brand available.
