I had a session with laser hair therapy where they botched the job and scarred me. When I reached out to Groupon they said since I redeemed the voucher there was nothing they could do. Yeah to get the scar I had to redeem it haha. They wouldn't do anything for me. I had pictures and the business admitted that they had messed up. Groupon will not help. Terrible company that lacks empathy and even a tiny shred of customer service.
