2 months later and query still not resolved.

So on black Friday I ordered a pair of sneakers for my son. Two weeks later after querying where my delivery was, I receive a call an email f4om zakirah Mahatey advising me that they over sold and do not have stock, and will replace my sneakers with a complimentary pair and refund my money. The sneakers were delivered in December, however the size was incorrect. I only found this out when I arrived back from holiday. I emailed zakirah on numerous occasions to advise her that the refund was never done and then emailed her last week to advise her of the size. I have since then sent an additional two emails as I have not received a response to the size , nor have I received a response with regard to my refund. It is nearly 2 months later and still not a word from New Balance. Very disappointing and frustrating to say the least as I distinctly purchased the sneakers for school for my son.
