No idea who this is, missed the call but it was on Good Friday (a statutory holiday) so I doubt it's a legitimate business. Also, when I tried to call it back, I got a recorded "this number is not in service" message.

they called asked for me heard something weird then they hung up and when i phoned back the number was not in service

I had this number call me on Family day "statutory holiday" but the call disconnected before I had the chance of picking it up.

got a call from this number hang up

their phone number in calgary is 403-543-1620.  i just phoned them to complain about the hang-up phone calls i regularly get from one of their phone numbers (the most recent one ending in 1627).  the girl took down my number and said she would request that my number be removed from their list.  time will tell if that actually happens.

Calls at all different hours. No message left.

phones and hangs up

Phones..then hangs-up.
