Warranty problem not getting sorted

I purchased a Ryobi Industrial Brush cutter from Makro in Port Eliabeth.<br> This is a Industrial unit that can be used for 8 hours a day, 7 days a week!<br> Well it only lasted about 17 months, and usage were about 1 hour every 2 - 3 weeks!<br> It broke and fell of my back while using it! <br> On 21 Dec 2014 I took it back to Makro. Repair no. ***.<br> They never came back to me. I had to call them several times and go there to follow up. <br> They always had a story!<br> If I remeber correctly, they promise to replace a product not sorted within 21 days. Well this they don't want to do!<br> On 10 Jan 2015, I apoke to Chan ( manager! ) at the branch, and I got promissed it will be sorted.<br> Nothing happend.<br> On 17 Jan 2015 I phoned and spoke to Jasiem ( manager! ). HE PROMISSED me he will sort it and come back to me. Well a month later, nothing!<br> Today, 14 Feb 2015 I phoned again, Jasiem buey with client, but Natasha ( manager! ) spoke to me. She will follow up on Monday with Ryobi ( Russel ). According to them Ryobi shipping the part from JHB.<br> Maybe using a snail to ship teh part, because itws going for 2 months.<br> Don't know if I must beleive her! Just empty promisses as always!
