Poor customer service

I bought 2 items cash. 3 piece bedding and boys bedding I asked them to cancel the boy bedding after paying cash in the Nelspruit branch they said the order was cancelled an I will receive my refund within 5 working days it's been three weeks Now and not yet received nor a call from them why the delay. It's very poor customer service for my first purchase will not support them again will also inform my family and friends about my service received.
