Pathetic service from Lewis store

They deserve zero stars. My sister went to laybe a kitchen unit worth R13 000 in july and in October she went to pay balance of R9000 and they promised to deliver the kitchen after 2 or 3 day thill this day. My sister went back to the store and they said the kitchen unit is no longer available and now they are offering her the money back! We do not want the money we want the kitchen unit that was paid in full when my sister check online she can see that the kitchen unit is available still but its more than R13 000. The branch is idutywa they treat people like fools because we are in the rural areas. This is a gift for my mother who not so long ago had her husband passed away. This will make her happy but how when these people refuse to deliver?
