Bests & Worsts Reviews from Amazon

I purchased this dolly about 2 months ago. It worked great until about 2 weeks ago, when i noticed the stitching was coming undone on the flap that holds the canvas bag to to the dolly. If the bag cannot stay attached to the dolly, it's useless. I tried to return or exchange it through Amazon, but it's been more than 30 days. I'd love to have it replaced or repaired. If i hear back from the seller for a replacement or repair, I'll update this review.
