I have been receiving calls from (647) 258-5537 for the past several weeks, and I always hung up after a few seconds

Called many time during the week for the last 3-4 weeks.  Before, during and after business hours.  It feel as someone is checking when I am home to pick up the phone.  They never speak or leave a message.  Just listen for a few second and hang-up.

yah I knew one of the agents there but I had already a free estimate from them and it's nice......and i wished they'll not be calling me anymore

I got (647) 258-5537 very day, I can not remember the company's name

I also received calls from this number. Its nice to know who these people are.
I wont answer this number.
