I had a problem w mice so I called terminix (a name I recognized from TV).
Here's what happened:
Called customer service (central location that books out to branches) and setup an appointment. Scheduled next day for a technician to show up during a several hour period (think cable guy business model). Took the morning off work... Waited... Waited... Waited. No one ever showed. Called customer service (on hold for 20 min while they called the branch ... Told me I cannot contact the branch myself because they are "forbidden from giving out employee phone numbers"... Whatever that means) customer service then told me that the branch manager would be calling me shortly to get someone out. Proceeded to sit at my house for the rest of the day and never heard from the manager (Mitch?) who was supposed to call. Whole day wasted, never saw or heard back from anyone.
Called CS back and they told me someone would reach out in the next 24-48 hrs... No thanks.
Couldn't tell you how they actually do when it comes to exterminating BUT I can tell you if you're looking for the "we don't care AT ALL" about your business, business model - this is your place!
