QVC review: Philips sonicare expertclean 7700 toothbrush with/ uv sanitizer

On 5/27/2021 I was watching the qvc, tv show and the host and hostess brought out the philips sonicare toothbrush with sanitizer. They were offering the toothbrush unit for $99.00 and told the audience that the company that manufactures the unit (philips) was offering a $20.00 mail in rebate. I bought the toothbrush unit and put it on my qvc card by synchrony bank that same night. Today, may 2nd. I received a package from qvc containing the toothbrush unit and a rebate form for $20.00 from the philips company, the promo code was 20-20781. The expiration date to mail in the form is june 30, 2021, but under conditions for the offer: the sonicare toothbrush must be purchased between september 1, 2020 - april 30, 2021. This rebate is expired! Qvc was either lying or made a mistake on the dates of this rebate. The did this on tv in front of a national audience and they sent me a rebate form that is expired and useless. I feel that I was mislead and cheated out of $20.00. I called the philips company, rebate department and they will not honor the rebate. Please help me. Qvc's customer service phone number is: [protected]
