The San hair selling bad quality weaves.

Bought my hair towards the end of last year at The San hair Mall of the south ,Wore it a few times and the closure started falling off, I then returned it and they fixed and wore it a few times and the hair on the closure started falling off again, the quality was just bad and when I returned again for them to fix it, they told me about a 7 days return policy which made no sense to me honestly because what if I bought for a future occasion. The San hair sells low quality hair and they don't wanna fix my hair now which a need fixed because I spent a lot of money buy that weave.
