poor customer service

I bought shoes on mother's day at foschini. Following Sunday I wear them n realise they gave me the same shoe (4 same foot,left).I went to the store, Zanele1 doesn't greet me.i then explained to her,n she says 'thank God it's not me'.then she's busy with her colleagues up n down looking for the shoe, then calls another customer.she then says to me,do u hv ur card with? I said yes.she she says pls give it to me. Why? I asked again,she then says they need to reverse money back in my acc.i told her I don't want my money back,I just want the shoes.only then she tells me that they don't have the other shoe,that size in store.i then asked how is it possible that two ppl ddnt c this (lady @shoes dep. N Susan @till).then asked her y she's not apologising least 4 da inconvenience,she says because I walked away. Now I don't know if I looked like a fool to her or if she was trying to cover up for herslf since there was now another colleague next to her,cause I walked away because she had called another customer.i liked n appreciated what zanele2 (authorising) did,she asked what happened n looked at me n said 'askies'. Thats all I wanted.cause my time n money was wasted.
