Really disappointed with my recent shopping experience online from Australia. Bought a pair of shoes for my son online. A week later the wrong shoes turned up (the box had the right style code but the shoes inside were a different style code). Contacted nike.com and was told I have to return them and re-purchase. Not happy that I had to pay for a second pair before my first ones refunded but didn't want my son to miss out. A week later, second pair arrives and their wrong again (again right box, wrong shoes). So I contact nike.com again. They are apologetic but tell me I must return and re-purchase. They will speak to their warehouse to ensure it doesn't happen again. So I buy my 3rd pair and still have not been refunded for the other two (although I have now) and they arrive WRONG again. Same issue. Box has the right style code, shoes inside are wrong. What on earth? So I contact Nike AGAIN. They say I need to email the warehouse and they give me an email address. I email the warehouse and they tell me I have to contact Nike.com directly. OMG! So I ring Nike AGAIN and the person I spoke to was very apologetic and explains that he's escalating my issue to the supervisor. The supervisor is currently busy but will email me within an hour....that was 48 hours ago and I haven't received anything (yes I've checked my Junk folder), Seriously Nike. Come on. Is someone going to send me the right shoes? Or even speak to me???????????????
