Bad Service / Faulty Product

I went to purchase a DSTV Steama at Makro Arbor Crossing. It was difficult to find service, and when I did, the staff were not friendly at all. This was at around 10am on a week day when it was quiet. I asked if they could test the device for my friend had an issue with his device he purchased from a different store. They staff refused to allow me to test it. I have now got home and the device is faulty. I stay 40km from the nearest makro to me. I find this service a disgrace considering the size and so called reputation of the group.
