Trimtech Lawnmower and Marko bad service d

Had the worse experience ever and it was my 1st time buying from Makro. I will never purchase at Makro anymore as they **** on their adverti*****t. I bought a Trimtech Push Lawnmower online on the 21st January 2024 it was delivered on the 24th January 2024. I assembled it the night of the 24th January 2024, we used it on the 25th January 2024 and it did not want to cut more than 90% of my grass as it is thick grass, some of the grass was long it did not want to cut it at all. Even while cutting the grass, the *****s constantly fell out. We sent an email on the 26th January 2024 to the online customer service and explained that this is what the Lawnmower do and what can we do to exchange it to a Lawnmower that can cut our grass. The 27th January 2024 Hlengiwe phone and told me that the Lawnmower must be booked in for as*****t before they can give us a refund, so I told her that I will take it to Makro Bloemfontein because on the invoice it is showing that it was invoiced at that shop. On arrival to Marko on the 3rd February 2024 that is before the 14-day return policy, then they also told us about an assessment thst needs to be done, we explained to them the Lawnmower is working but the only problem I have is that it is not working on the grass I have, plus the *****s are falling out when cutting, mind you on the online shop it is saying this product has a 1 year guarantee and not a warranty. Today on the 20th February 2024 I recieved and sms stating that I must collect my Lawnmower at Marko and that it was repaired successfully. How do you repair a product that is under guarantee and it was working, now they are telling me that it was assembled wrongly by the springs of the machine, I spoke to Marko and the technicians of Trimtech and we asked them what must I do with a Lawnmower that won't help me cut my grass and we explained how many times to them that we don't want the machine we want to exchange to a other machine, all that they told us there is nothing that they can do if we bought it online, we must just collect it. How can you tell an unhappy customer that. This means I have paid R1799 for a thing that I will not use, because of incorrect information given of the product online. Very unprofessional people that assist us, only 1 person that atleast tried to assist me is Desiree at Bloemfontein customer service. Really not happy with Marko.
