Extremely poor service from RangeXTD

I bought a range extender in January 2021 and the item is still not delivered. The company provided a tracking number but according to my tracking app the product on the way bill was delivered in Hong Kong even when the destination says South Africa. I contact the company via email more than 10 times and all I received were excuses and promises to allow a 20% discount. I requested refund but to date no commitment was received to an extent I believe it was a scam
