Appauling service and dishonesty from sneakercrib

I purchased a pair of takkies in December, i had to return them at my own cost which was not an issue. Since then, i have tried to get them to replace the takkie. I have sent over a 100 e-mails. They donot take my calls, or reply to my watsapp messages. Every week i get a message saying the takkie has been dispatached which is a lie. Please donot ever puchase from them. They are dishonest and the service is appauling to say the least.
