unacceptable customer service

Hi<br> I had a very weird customer service respond on the 12.07.15 when i went to return my duvet cover set. I bought the set less than 2 months ago of which still have the reciept but i had it for 2 weeks on the bed then thread started to come out in the middle of it,so since @home has 6 months quality guarantee i went to @home zevenwacht mall of which is where i bought the set. So the lady who handled my complain said am the 1st person to complain about the duvet set,even asked me how did i wish it i then rep**** with washing as that is how i wash all my stuff. She then said she will phone the quality control and find out what she should do and will phone me on Monday or Tuesday but what surprised me is that she returned the set back to me. So is this how the 6 months guarantee work that when i have garment problem i must take home and will be contacted about the decision so the quality control will make decision based on what if they don't see the fault. I am really disappointed in this whole thing and i doubt will ever buy bedding because they have policy that is so confusing when is time to be used.
