Treating the elderly very BADLY

My elderly mother bought a DEFY microwave to the value of R1499 cash. She does not use cards - she prefers withdrawing the money then paying. UNFORTUNATELY she lost her purchase slip and now the MICROWAVE is broken. The microwave is still under warranty.

Through your customer care line I was informed that there is a way to track my mother's purchase but she'll have to provide specific details. Fortunately she remembers the details. We provided the floor manager (Anna Sekgothe) the details: We have had NO RESPONSE from her to-date. However the said manager said the people at the customer care centre DO NOT KNOW WHAT THEY ARE TALKING ABOUT OR HOW THE SYSTEM WORKS?!?!

Can someone at GAME assist us with this please as no one at Southgate has contacted us?
