Very Unhappy

I bought an electric blanket on the 28th of October 2023 Order # *** and when I tested it some days later I noticed it wasn't switching on. Contacted online shopping on the 8th of November advising them that the blanket was not working which they said I should return it back to the store. On the 19th of December I followed up for my refund and didn't get a response until I followed up the second time on the 2nd of Jan 2024 and Sannah rep**** with a form for me to complete for the refund. From there I never heard back from them and after countless email follow ups I decided to call the online store today and I am now being told that I had used the blankeT so they cant refund me until they hear from the supplier, mind you I bought this blanket in the middle of summer and I only opened it to test it before packing it away. Now they are saying it was used, seriously???? I need my refund please and I WILL NEVER EVER BUY ANYTHING FROM THIS STORE AGAIN>
