Dirty/Worn sneakers

I bought shoes online at XTREND SANDTON Shop BC 27 ,thier rep Kgomotso Manyama decided to send me dirty sneakers that has been worn previously with very bad stains and the sole shows exactly that they have been worn, i sent them an email with pictures and videos but they never got back to me, they are not even picking up calls. I believe they took advantage because m staying in Kimberley.
