I got a Groupon for these guys for $25 for $75 worth of carpet cleaning (basically one room). Seemed like a good deal.
I didn't need it until about six months after I purchased it. I tried calling and leaving a voicemail, and got no response. I then tried emailing. After my second email, I got a response back saying when they had available, and I said I'd take that spot. I didn't receive a response back, but assumed that I was booked.
When I didn't receive a response, I called in the day before the cleaning, and actually got through to talk to someone. They were very apologetic, but said they had no record of an appointment for me for that day and were booked up. They made another appointment for me three weeks out which she verbally confirmed.
I didn't receive a confirmation the day before though, as she said I would. I tried calling, and again, left a voicemail to which I got no response. I waited for two hours for someone to show up for the appointment, and no one showed up, and no one response. This time, when I tried calling, the voicemail box was full.
I asked Groupon for a refund of the Groupon. Thankfully, Groupon itself was very great about it. They wrote back immediately saying the Groupon was refunded and they gave me an additional $10 for my troubles.
I would definitely advise people stay away from these guys, and to really research companies on Homestars or elsewhere that are offering coupons on daily deals sites.
