Getting about 2 calls a week from this number and no messages ever, dead air and always get 'the number you have reached is temporarily unavailable'

Are these call legal?

it's for windows and doors. He had a heavy accent and I could not get name of company even though he repeated it. It's in North York

Windows and doors place. Offered free estimate on any windows or doors we were thinking of replacing. Didn't quite get the company name...  but "delux" was in it.

me too.  

I have received 5 calls a day with a number. It is so annoying and they do not even reveal who they are! Thanks for the above messages! I tried to google who they were but it did not appear!
