MAKRO DON'T DELIVER

We bought a Nikon Camera in February 2015 from Makro, May 2015 we had a problem with the camera, the camera does not read the memory card. Makro fixed the camera without any hassles. December 2015, the same year and a few months after the purchase and after the repairs, we had the same problem, which is camera does not read the memory card. And guess what? We get billed for R3500???? How ridiculous!!! Same problem, but they charging us. How is that possible? We were warned about Makro and stupid of me still proceed with the sale. We are busy with legal steps, a camera that cost us R8000 and we must pay for repairs? Why did Makro not charge us in the 1st place because the damages are the same? So so furious with Makro, my daughter will be in her 3rd year this year and she is using this camera for her studies, she is studying Journalism. Be careful people... make 100% sure where you purchase your equipment from. I mean.... the problem is exactly the same as the previous time. Can someone explain why i must pay for repairs? <br>
