Makro pathetic quality products and aftersale service

I bought a stepper online. On the day I unboxed it I let them know the adjust knob was broken in pieces inside the box. Exactly 9 days after I received the product the supposed steel frame of the stepper literally broke in half and I'm not anywhere near the maximum weight. I immediately booked a courier on 25 November to send it back to them. The courier was supposed to pick it up on 28 November. I'm still waiting for this pick up. I've sent numerous emails and phoned as well and every time it's a different excuse about them apparently booking a courier or trying to get the courier to pick it up. I've sent emails every day this week requesting a refund. They should not even bother to pick up the broken stepper, just give me my money back so that I can buy from another shop with better quality products. They now ignore my emails. I see there's no way makro is going to refund me or pick up their poor quality product. They sell pathetic quality and expect people to just lose their money in the process. There is no customer service or help if any kind from Makro. I don't know what's worse; them basically *****ing money from customers, their poor quality they sell or that fact that they don't give a damn about clients after they have sold you something.

All I want is my money back so that I can buy a stepper from a store with better quality.
