Shocking service!!

Shocking after sale service! Receiving my shoes was very quick, I received them with one of the laces broken is am not able to tighten them. I did a return request and was informed for the shoes to be replaced I would have to pay R350 for handling and processing cost. I informed them that I'm not happy with this as the shoes are not wearable and now have not had a reply from them for 2 days. No telephone number in South Africa to contact to try and follow up on what is happening with my faulty order!
