Item exchange dispute

Good afternoon, to whom it may concern.

My name is Slade Scholtz.

I bought a Ultra-Link 19"-65" Swivel Tv Mount Bracket. I called the game store at N1 City Mall and Spoke to the Branch Manager Juvan. I explained that I bought this product but did not need it anymore as I put my Tv on a Tv Stand. I explained that the product was still sealed and never opened and that I lost my slip. I explained that I was in the store but one of the ladies told me that he was busy so I decided to call instead.

I've been calling since last week Thurday and every time Mr Juvan said he would call me back but never did. He also gave me the excuse that I had to wait till Monday morning for the returns lady to return back to work.... I called him again now today being Monday morning and Mr Juvan promised once again he would return my call but never did. Now that I called again Mr said I can't return the product without a slip when I said that in the beginning and I said I don't want any money back, I would like to swap it for other essential items...

Now I ask.... What kind of customer service is this??

I would like a prompt reply.

Thank you. Slade Scholtz ***
