Should I be worried?

Last 4 months ago my class decided to give back the tshirt that a shop made us since there's been some mistakes done in the tshirt and the shop owner itself said that they would stitch the back again but they won't replace it with a new shirt and were completely fine with it so we brought it back to them and now its been 4 months closed to be 5 and we still didn't get our tshirt back so should I be worried or nah? Cuz idk how long it actually takes to stitch the wordings again

Also they've been telling us that it'd be ready next week yet they still hadn't gave it back to us
It also cost like a shit ton of money
