Makro is still confused

Further to my previous review below, Makro sends me an email saying they will send a technican. i ask why, they don't respond. I call to ask, they say they will find out. They still send a Trojan technician. He came through yesterday, 14 June, took photos of the digital error code and completed another assessment. And now I don't even know what to do? lol. It's like you guys have not understand the review below.

Dear Trojan and Makro • I purchased a Trojan TR300 Treadmill from Makro online (Invoice no 34 dated 11 March 2022) • Item was delivered by Crown Mines (Proof of delivery Mak********** dated 17 March 2022) • I used the item about 7 times • In May, the treadmill stopped working and error code E01 appeared on the screen before shutting down • The item is under a two-year warranty and the booklet mentions to contact the manufacturer for issues/repairs • In mid-May, I called Trojan and explained the issue. Lorraine was helpful and logged a call with a technician. Around 23 May, a technician came out and assessed the machine and said a DB board needs to be ordered. Within the same week (25 May), a technician came, replaced the DB board and tested the machine. 👏 • On the evening of 26 May, I try using the treadmill and even more error codes show up (ranging from E01 to E13) before shutting down. I emailed Lorraine. No response. • I called Makro on 27 May and explained the issue. I said that this machine is basically brand new, I paid R6 999, and I don’t want it repaired again. I want it returned and to be give a full refund. I was told that they have to log a call with Trojan to do an assessment and to confirm that the item is faulty. • A technician came through yesterday, 8 June. He said I will receive a link and he will submit a report that the item is faulty. He said he can see that the item is new and barely used. • I called Makro later on the day to find out if they received a report. A lady seemed very unhappy and said I should call Trojan and ask them. I called Trojan and spoke to Jane. Jane was helpful and understanding and said she will send an email and ticket to the service centre team. • Today, 9 June, I got another SMS saying I have been assigned a technician who will contact me. But I don’t want another technician. I want the item to be collected and for me to be refunded. Dear Trojan and Makro (ESPECIALLY MAKRO WHO MADE THE SALE AND REFUSES TO HELP). Please stop treating your customers like fools 😊 and pushing me from pillar to post. Kindly allocate ONE person to RESOLVE this and give me my full refund.
