Contact & support FAQs
A few quick answers to common questions before you reach out.
How quickly will someone respond to my message?
Response times depend on volume and the nature of your request, but most inquiries receive a first response within one business day. Include your preferred contact method for the fastest follow‑up.
Should I use the form or call by phone?
Use the form for new services, quotes, and non‑urgent questions—especially when you can share helpful detail in writing. For urgent issues with existing services, calling during business hours may be faster.
Can I schedule a meeting or site visit?
Yes. In your message, mention that you would like to schedule time and include your preferred dates, times, and whether the discussion should be virtual or on‑site.
What information should I include for a quote?
For quotes, share your locations or ZIP codes, number of users or seats, target go‑live dates, and any must‑have requirements (like speed, reliability, or specific services). This helps narrow down suitable options quickly.
