Disappointing treatment

I put a lay-by for a TV Stand @ Bradlows Randburg & I was assisted by Sam who was extremely helpful & I was the happiest person on earth.. Until I settled the bill. After settling the bill, I was contacted by the warehouse to deliver, however they had the wrong delivery address. I called the Randburg branch & I was put through to the manager DAVID HANDERSON, who had a disgusting attitude. He spoke to me like I was an irritation to him & was not helpful at all. He said he had rectified the error, however, the warehouse called again & no changes were made. I called the store with my own airtime to inform them that nothing has been amended & he said he will rectify the error, again. When I asked my fiance to call him, he gave us the details of the warehouse to call them OURSELVES, where we were told the manager had to call because they don't deal with customers directly. When I called him, he was so annoyed & told me he will not help two people all at once (me & my fiance) & asked if there's anything else with such a bad attitude. I won't buy from there EVER AGAIN. I hope the JD Group does something about this. This is NOT how you treat a customer DAVID. Thank You SAM, great service!
