Makro Silverlakes very poor services

I will never in my life shop at Makro Silverlakes ever again, the customer service is so horrible, i have been trying to return a xbox item for the last 6 weeks as the makro team return department are very ***********. Finally when i reach a manager (Quote on quote) he started yelling at me the customer and when i started yelling back that how dare he shout at me the customer i proceeded to tell him to get the store manager to which he tried making the situation race based implyimg what is wrong with him being the manager which is unacceptable, makro up until this point have done nothing to assist, today i was told by their helpline we cant reach anyone at the Silverlakes branch we will need to go into the store for a third time what a joke. Do not dare try and call their helpline as 99% of the time the line will drop or they wil make promises to have someone contact you which either never happens or the person contacting you cant help as they are not at all revelant to that situation yet makro keeps putting them up to calling me.
