Wig issues

On the 9th of May 2015 I went and bought a Wig @ one of HairCity,s branches - NEWTOWN JUNCTION. <br> This is a curly wig therefore the curls have to remain the way they are. I asked about this and was told that if after a month the curls start to disappear I should spray the wig with water, then moisturize it, it will then curl again. <br> I wore the wig for a week one day went out to a windy weather and when I came back the curls were disappearing. <br> I send them an email, they did not respond. I then called them on the 21st of May 2015 at their head office in Collet drive and spoke to their manager by the name of Tumi she advised that she will send somebody who will collect the wig, they will then see if it can be fixed failing which I will either have to choose another wig or opt for a refund. <br> They did not pitch so on the 26th May 2015 I called again and left a message for Tumi who was out at the time of my call. I was advised that she will return my call. Up to now she has not. <br> I don,t know what to do as I only wore the wig for a week only and it started falling apart.
