North Coast Medical Comfort Cool Thumb CMC Restriction Splint - Right, Large - Model NC79567 - Each

I ordered a large splint for my hand since my medium splint was sightly too small so I thought to try a bigger size. I was sent a large plus size splint which is useless to support my hand and wanted to exchange it for the right size that I ordered. It seems that this is not possible. I will have to report this to trading standards since the purchasing contract has been broken and not addressed to fix the problem. It is important since the splint does not function as required and was expensive.
