Poor quality(workmanship) on baby clothes

I buy most of my 10 months babies clothes at Ackermans and I love the selection they have for boys but more and more I am becoming unhappy with the service and more so the quality. Between work, sleep deprivation and taking care of my baby I really dont have time to be taking back clothes due to poor workmanship! These are baby clothes, babies grow all the time so all im asking here is that the clothes last for the one month that they can fit my son. I bought a gown 2 months ago at the Ackermans in Vaal mall, winter started and two weeks ago my son started wearing the gown and its the stitches have come undone on the hoody leaving a big whole. Again i bought takkies, and they only started fitting my son now and on the very first day the stitch has fell out. My son is not even walking yet, there is really no pressure to these shoes and the very first day the stitching has come undone?! This is really unacceptable.
