Bad quality an no reactrion

I Bought 3 Extra Blue Unique 4 way stretch jeans, the first one I bought was during March this year. Only 4 month later - and I didnt wear them so much - they show signs of damage on the stitches between the legs. All of them !! It cost me a fortune and now Sissy Boy dont even respond to my emails ! This is not my first Sissy Boy - all my jeans are Sissy Boy - but this is the first ones with this problem. Sizes are the same and isnt too small. I am very disappointed and wont buy a Sissy Boy again !! They dont even answer the phone, they are only rining non stop !
