Donna poor quality

I'm dissapointed in the quality of Donna's clothes. I purchased four maxi shirt dresses online around October - November 2018 not sure of the date as it was purchased on my moms account. I have worn the dresses but made sure that i do not wash it every time after it was worn. Three of the dresses is tearing on the sides and at the buttons or pocket side. after all these dresses cost R 599 each and one expect it to be of good quality. The quality of the dresses is not up to standard.
