Bad quality and customer service

I bought a wig at the San Hair waterfall Mall on the 14th of September, got it installed on the 22nd and a day after the hair was falling out and was even Harder. Called them and informed them of my experience, and I was told I should return the hair. Did return it, few days later I was told that my wig was treated and I should come to collect it. How do you treat new wig? The quality of the hair is not what we are promised or what they are promoting. It's my second time having to return their hair because of the bad quality hair they are selling. Even today I am still struggling to get my refund from them. I would not advise anyone to buy hair from them and even their customer service is very poor.
