Stellensolar.co.za a scam

I bought an expensive lithium battery for solar use from the website stellensolar.co.za. they were very friendly The battery was on special for about half the price at other places. I made the payment by eft.that was on 29 Oct 2021. Since it was a long weekend I gave them rope until the next Wednesday before I called to hear when the delivery will take place. After I called several times finally they answered and asure me I will have my battery by Friday. Friday came so did Monday (8 October) they don't answer their phone or whatsup. This is a scam, I wonder how many people fell for this. Can you help me to get my money back?
