Pro Carpet & Air Duct Cleaning

I got some of the worst customer service I’ve ever experienced with this company, and never even got my carpets cleaned.
I purchased a Groupon for this company last year, spending about $ 75. About 3 weeks before the Groupon was set to expire, I called to make an appointment. I think the phone number is someone’s cell phone that he answered «Hello.» After determining that who I was calling was, in fact, Pro Carpet, I asked him if I could make an appointment to redeem my Groupon. He said he was on a job and to email them. I emailed, asking for a specific date so that I could redeem before it expires. The response was simply a phone number. No salutation, not explanation. So I called and left a message. He called back and told me the next available time was not for another month, after expiration, but they would still take my Groupon. We traded several emails and phone calls over the next few weeks. I asked repeatedly if any weekend dates were available and he continued to send me week days that I am unable to make work. All of his answers were short and impersonal with no explanation. One of them was actually gibberish. He finally stopped responding to me after about 5 weeks of me constantly following up.
Guess they just wanted to take my money without doing any of the work. Thanks for nothing.
