Very professional and in an acceptable time framePosted on Google Aaron PeckTrustindex verifies that the original source of the review is Google. I reached out to OxygenIT about their services and got a fast response. I meet with Tim and realised that OxygenIT wasn't the right fit for my business at the moment. But Tim was genuine and helpful, even refer me to someone else that might be more suitable. Can't ask for more than that.
