Rogue Tube Bands

I used these 2-3 times a week for 4 months and a hole wore through. I pretty much only did rows while sitting with the band looped around the leg of my coffee table. Pretty normal stuff. Customer service won't replace the worn band because it's only covered for 90 days and they also told me not to use it because it could cause injury. I sort of expected expensive bands like this to either last longer or have a better replacement policy for normal use
