Power Pocket Workout Leggings

I have MANY pairs of these tights, I wear a small, sometimes the small fits like a medium in the legs, a small in the waist and vice versa. Sometimes size medium fits like a large, sometimes is a proper medium, other times it fits like small. The checkered ones were so tight around the ankle opening I could barely get my feet through the openings. And the newest pair--the orange/blue wave design bled--some of the greyish purple bled into the the white sections making it look tie-dyed. That's a first. I'm still waiting for customer assistance from orders placed back in end November/early December--received wrong tights in one order, which still hasn't been refunded etc, and then a security tag was attached to another, with only option of going to a store that does not exist anywhere near me. Not sure what's up with SB these days, but I hope they fix it. I realize where in the midst of a pandemic, but other stores (athleta, Lululemon etc are not having these issues).
