Trojan and Makro

I made an online purchase for a Trojan TR100 treadmill last year September. It got delivered with a light crack which I didn't query because I didn't want to go through that trouble. 2 months back it started giving problems like"slipping" and burning smell from the motor. I use the treadmill about 3 times a week and I'm the only one using it. It's fairly new and I believe it shouldn't be giving problems right now.

I reported it with Trojan who wanted to send a technician to repair and I refused. I want the item replaced as this is going to affect the warranty on the item. Trojan said I must escalate the issue with Makro, which I did. They mentioned that they have to send out a Trojan technician to come and assess the damage first. I received a few text messages for calls logged, but no technician pitched.

In the meantime I can't have proper Excersizes because of health issues and safety. My health is deteriorating while waiting for both companies to sort out their mess. I feel that they must refund me so that I can purchase another brand of equipment.
