I have no idea how they have functioned as a company this long. We are a contractor and have purchased another company which was signed with Vixxo. As a result, Vixxo called us for services. We explained we were a different company at the start, signed their vendor packet with necessary forms, did a few jobs. Got paid after half a year and several calls about past-due balances, but to the wrong company name! We've reached out over 15 times over the course of a year to get them to change our company name and send payment with the correct information, each time they assure us they'll take care of it and it never happens. They still call in regularly for service requests, which we explain why we are rejecting it and instead of fixing it they say "okay thank you" and hang up. After a year of dealing with this, we finally get a call from a competent person (a manager) who seems genuinely interested in solving the problem, of course they drop off the Earth with no contact information and the issue is not resolved. You will never speak to the same person twice, you will likely never get paid, they are by far the most incompetent company we've ever worked with. Save yourself the headache, avoid working with this company.
