Management not willing to help

Wanted to return quality defective sissy boy sandal which was bought on 31/01/2015 and was hardly worn by my wife and when she wanted to wear again this summer she discovered the whole strap had come loose from the stitching.The staff member at customer service just took a look at date on slip without checking the value of the item and said the 6 months had expired and said she will call a manager.Noxolo Nonxuba the manager on duty already had this attitude on her facial expression she is not going to do anything and just pointed to the board saying 6 month quality guarantee. According to her this has always been the policy when I know these terms were only updated this year.She was going to do nothing to assist and did not even look at the item or slip and maybe say that is the general policy but she will follow up with sissy boy.These people who are now managers at Edgars lack customer service and do not honour the Edgars name.In the past the item would be assessed by customer service and if it was a obvious quality defective item even way after 6 months Edgars would credit because the Edgars name meant quality.I am a customer for almost 20 years and this is not the Edgars I know
