Got 2 calls from this number within moments of each other.  first call showed up as 'UnKnown' with the number. Second call shows up as Seon Light.
It was the same man each time wanting to speak to the business owner.  When I asked what the call was in regards to he kept pushing to speak to the owner.  I finally did get him to tell me what the call was about : website design.  When I told him 'we already have a website, but thank you....' he insisted that we needed one and he'd like to speak to the owner.  I was polite and thanked him assured him we have a site and are not in 'need'. I finally got him to hang up.
Within seconds he called back...same song and dance.  I simply said "sir I just spoke to you.....I told you the owner is not available and he'd tell you the same thing.....we already have a website.' It took a bit but he hung up.
A+ for tenacity! too bad he doesn't put that effort into something legit and useful.
