Makro Online refund 2 & half Years!

I bought 2x gas Geysers in October 2019 and was fitted in November 2019 only to find out that the gas Geysers was not working at all. We had experts out and also find that its a geyser fault.

I then send it back (Makro arranged courier) on the 22 of November 2019 it's now the 2nd of June 2022 and no one has ever called me back or even send a mail of the progress. I left numerous of emails with NO reply, I went on their Facebook page to leave a comment that's when they respond the 1st time. Telling me I would have my refund paid back to me....without taking my back account details. I have recently ask why my refund was not been paid out...but with a reply that my funds will be in my account in 2 days. It's now been a week again. I mean it's almost 2 and a half years waiting for my refund. I'll NEVER BUY @ MAKRO ONLINE AGAIN. AND I NEED MY REFUND.....HOPEFULLY THIS WILL SHAKE THEM UP AND PAY MY REFUND

I did phone a few times for follow up but no one could assist me with an update.

What must I do??? I'm sitting at this moment without hot water for over 3 months now.

Please assist me.
