Edcon/Edgar's poor service/Incompetence

I bought a pair of Nike trainer shoes for my mom at Edgar's Fourways Mall she loved the shoe so much and I was happy to purchase one of the shop assistants went to fetch the box fo us and we paid for the shoe, when we got home, our shock was to discover that both shoes are right footed. We had to drive back (Petrol costs) when we got to the store they told us they no longer has stock I should refund or check for exchange at any other Edgar's or Edgar's active the store couldn't make a call since Edgar's contacts recently changed, I didn't want to disappoint my mom I drove to Diepsloot mall (Edgar's active) that's another cost in travel incurred. Edgar's active sent us back to fourways mall since they don't exchange fo Edgar's something I believe should be common knowledge at Edgar's meaning should we have been advised well all this would have been avoided all I wanted was a pair of sneakers for my mom now I had to deal with Edgar's incompetence this is surely my last dealing with Edcon related retailers. I don't want a refund I want a pair of this specific Nike sneaker that's all and the costs I incurred traveling up and down with a single phone call I am certain I wouldn't have had to waste fuel. I am really disappointed ?
