"Makro Online" More like you put your "Neck On The Line" when you buy from them.

I bought a router from the online. The one that I wanted to buy was not available on the day I decided to purchase the router so I decided to take the second best one according to my needs. Upon receiving it I opened it and tested it and found that it was the wrong one. I bought the wrong device. I contacted Makro and the consultant over a period of two weeks made me understand that would be able to collect it and provide me with a credit to my credit card. This was repeatedly said to me. The delay came when I had to wait for the supplier to scrutinize the photo I was asked to send on several occasions. Just to receive a response yesterday that the supplier says because I opened it the will not accept it. Given that it is the supplier refusing to accept the returned item this is in effect Makro saying that they do not care enough to intervene. I have purchase numerous things online before but this is truly the first time this has happened to me. I am keeping calm but still remain truly disgusted by this cause if I bought this in store this problem would not have existed. Someone please Help
