You haven't caused me any confustion - no apology needed.
The truth is that you are not going to reach Petar Vucicevich at any of those telephone numbers. The only result brought about by calling Sulja Bros lumberyard, Kore, IBP and Sams will be to disrupt their normal course of business and will not result in any callback have any idea what he is going to do, and they are best left alone to get on with their businesses. I know it's frustrating but that's just the truth of the matter.
