Rain please refund our money

Ever since I had bought a 5g router from the company on the 26th of January, still even today our router isn't working and we optioned for a refund eventually but still we haven't received our refund and we have been taken back and forth trying to resolve this issue we now entered a new month and there still isn't any progress and we need that wifi working because we running a business which needs wifi connection. It's been a headache working with rain , all I want now is my refund of R699 and we'll find ourselves another service provider
