poor service

I'm writing to u Nita(Sales Manager)What a poor service from Makro Centurion. How can they fail to exchange something that was never used&was bought from them with proof of receipts still in place? They failed to provide world class service. Again they had to lie saying they've tested the hoob of the stove we bought. Thats unfair, bear in mind now that we know of consumer rights. Next time u won't win...never will i buy from u any more
