Awaiting Refund since April

I ordered online and paid in Apri for 2 pairs of boots which showed in stock. I then received an email to say that only 1 pair is available I then asked to be refunded for the 1 pair I'vebeen asking for my refund since April and still waiting. Lee-Ann now tells me to phone their finance department Please help to get my refund which is over R400!!! Most pathetic online service
