Bad Customer Service

My Wife ( account holder )wanted to buy a pair of shoes however the store only had one sze 5 of which one shoes was size 5 and the other a size 3. The manager informed me that Cavnedish was the only store that has a size 5 but it would cost R50 for delivery fee. I was asked to pay if she wanted the shoe. I did not think that it was fair that I was I shoud pay delivery cost if the the shoe we wanted was in stock and on the shelve but only had only shoe in her size. The shoe was not cheap and feel that the Foshni could have done more to ensure that we as account holders / customers are being assisted to.
