No response

I had recently complained about a matter where I had received headphones with my cellphone that were faulty. I had returned them to the shop of purchase where I was told that they would be sent back and I would receive a new pair due to the fact that it was less then 6 months and they are Skull Candy which have a lifetime warranty. Upon reviving notification that they had arrived I went to the store on the 12/12/2015. Only to find out that the manager had taken the original headphones and I was given a cheap line call Xqisit. I then asked where are the Skull Candy ones and was told they are the new ones. They had just taken a barcode from the skull candy headphones and placed them on the Xqisit headphones. I have been waiting since December for a reply as to when this shall be rectified but I still have not heard anything from anyone. Please can you get back to me with this matter.
