Whirlpool review: Refrigerator water filters

I accidently ordered the wrong water filters for my refrigerator. They arrived in a timely manner via P.O. [protected]. I called the filter department upon realizing my mistake. I received an e-mail from June, in the Consumer Direct Sales Team department. She instructed me to return the filters via FedEx asap. She provided me with RA #[protected]. The filters were sent back via FedEx Dec. 29, 2023. The FedEx Tracking Number assigned was [protected]. The package was sent to Whirlpool /Columbus/F315, 6241 Shook Rd,Lockbourne,OH 43137. FedEx told me the package was delivered 1/03/2024. After waiting a couple of weeks with NO REFUND to my Visa card, I made the second of four calls to inquire as to the status of my refund. After another week, I made a third call to the company. I was told that my refund was being processed. After checking my credit card account today, still no refund. When I called the company today, my original call with Erica was dropped. Please help me to resolve this issue.
