Apple service is non existent

I got an brand new apple iPod for my birthday 21 October 2017. Bought on the 11th October 2017. From the day I opened it it has not worked. Took it to Apple store in Grayston Sandton. They booked it in. Would not replace as it was outside their 7 day policy. Picked it up and it still did not work. My wife took it to Apple Store in Eastgate they PROMISED that if they could not fix the fault they would replace the unit. The first of two lies. I went today to pick up the fixed unit. I told them to test in store it did not work. This after they said there was nothing wrong. Is this incompetence or just plan lying? And no they not give us a replacement unit. So they did lie. So it is almost a month and non ipod. But they gladly take your money and then treat their clients like ****. This is not my only bad experience with Apple. I will never buy another apple product again. They have not integrity and no customer service policy at all.
