I just spoke with someone with an Indian accent. Really couldn't understand him and I pointed out that his number is captured on websites as a spam. He was unfazed by that. Selling marketing services but his diction was so poor, meaning he spoke quickly and didn't pronounce words fully that I really couldn't understand him.
You need to log on to the photon infotech website and click on the email link to email them and write: Stop calling 610-614-xxxx or whatever your phone number is and they will stop
Same as everyone else who has posted. Get calls almost daily. Leave no messages. Can't reach a human being when I call back, except one who doesn't speak English...
