Gadgetsul.com Won't refund purchase of a scam electrical device Montebello New York

I made an online purchase from gadgetsul.com in October, 2020 of a PowerPro (falsely advertised as an eneregy saving device), paying $59.99.  After plugging and monitoring the device in my home for three months I can positively say that I haven't saved a cent on my electric bill.  I have emailed contact@gadgetsul.com three times requesting info on how to return the device for a full refund.  They have not responded. 

I have filed a complaint with the New York City BBB -- but wanted to share my information about this company with Ripoff Report members as well, while I attempt to secure a refund. Note:  I have just seen an identical device being advertised under a different name by prime.goodletterfortoday.com.  It also guantees big electrical savings.  Incidentally, both devices are made in China and obviously imported by these scam artists hoping to make a fast buck.
