No response from online customer care

My brother bought me 2 pairs of running shoes in Gauteng (there wasn't stock in Western Cape where I live). They ended up not fitting correctly due to the special running soles I use. <br> <br> I've been trying to swap them for a different size but I can't get any help from the physical stores in WC because there's no stock here and it was a sale item (so can't be shipped from Gauteng - how is that a good reason?). And when I email them I don't get a response - I only get the standard automated reply \Our customer service team will be in touch within 24 hours to resolve your query\" ... and then nothing. <br> <br> At the moment all I want to do is talk to someone who can help me, but can't get anywhere. I've been trying for 2 weeks now"
