Poor Quality

I bought a pair of freddy wrap up cotton lowrise a month ago. I followed washing instructions ( I have 3 other pairs with no issues) yet they have started tearing at the seam on the pocket by the buttocks. I took it to the Pavillion store along with slip, they then sent it to Jhb for review and had their seamstress mend them (this took 2 weeks). I got them back and wore them once only to have them tear in the same place :( For what you pay for these pants its very disheartening to have the quality to be so poor. Perhaps stick to the wrap up denim as the cotton are poor quality.
