Refund outstanding for Trimtech lawnmower

I bought a Trimtech lawnmower for R2699,00 from Makro Centurion on 23 December 2015. I used the lawnmower twice and both times the lawnmowers wheels and undercarriage collapsed.<br> Due to it being holiday season I managed to return the lawnmower in the box on 17 January 2016. The unit was received by a Mr R Botha and I explained the problem to him. I also told him that I do not want a repair or replacement because the design is clearly defective. (There were two other trimtech units brought in on the same day.) he said he would have to clear the refund with the store manager. The manager explained that they would need to send the unit in, and I said that they could do that, but I want a refund, to which he agreed. <br> <br> The unit was send in on the 18th under repair/ref number ***. I followed up with customer care on the 30th of January 2016, as well as with the centurion branch who both committed to getting back to me today. I also e-mailed this exact complaint to Makro customer service on 2 Feb 2016 with no response received so far. <br> <br> I again followed up with Centurion who keeps on promising they will get back to me.
