Business ProfileforSpencer's TV & Appliance

My husband and I attended a Preferred Customer Sale at the new ********************** Camelback Location on November 7, 2023. We purchased the Whirlpool four-piece appliance bundle they had on special with the understanding that we were to receive a $400 rebate. We actually purchased a refrigerator we didn't need because this was such as "great deal." At checkout, I asked specifically how we get the rebate and our rep said, "I'll take care of that." We never received the promised $400 rebate. I have contacted our Spencer's TV sales person, ***************************** via email on several occasions since then. Twice he has responded with an apology and said he will take care of it. But we still have not received our rebate. I've looked at the ********* website and have searched for a way to escalate this situation to an executive within the company, but I can't find a means to do that. I feel that ****************** and the company misled us to believe we would receive a $400 rebate when purchasing the appliances. And I feel ****************** continues to mislead us by saying he will take care of it but never follows through. This is very disappointing to us as we did spend more than we intended to with the understanding we would receive this rebate. And the fact that we were supposed to be "preferred customers." Please let us know if there is any recourse we can take to get our promised $400 rebate.
