Gorgeous Hair — I am complaining about hair quality

I have ordered the hair in the month of February 2022 if rs.13500/-. This time quality was not yet all good, am really not satisfied and it's waste of money.when I asked to replace it then they told that within seven days need to return it.
Kindly help me on this, I don't want to waste my money..it's a humble to request either to return my money or exchange it
