Apalling service from Marko online purchase

On the 15/08/2017 I ordered for the first time online from Makro on their website a Ezviz Bd- 1402b1 8 - channel 720p Analog system with 4 720p Bullet Cameras. I received a Ezviz Vd- 1402b1 4 - channel 720p Analog system with 2 720p Bullet Cameras. Upon quering Judy at Makro she promised to investigate and come back to me. After a week of no response I phoned her again and she put me through to the supplier. They advised me that I have received the correct goods. I described what I ordered and what I have received but they insisted that I have received the correct goods and why am I speaking to them they only the supplier I should speak to Makro from whom I ordered. I was passed on to a manager at the supplier who also advised he will investigate and advise. After no feedback received I phoned Judy again and she put me through to the supplier and then I was told they out of stock they will gladly collect the goods and give me a refund. Which I didn't want. I checked Makro's website again and I saw that the product was still being advertised. Phoned Judy again she said that she will get back to me. Heinz from the supplier contacted me again and offered a refund again. I insisted that I want the goods that was advertised and ordered and he said he would get back to me. Obviously nothing has been done. Please can you give me contact details I can report this to as both Makro and the supplier obviously does not care about the customer as I'm left on my own with no solutions in sight.
