i think the company is called APS -  not ATS as mentioned in my first post.
i can find APS when i google....

Yolanda called today and demanded to speak to the owner.  I kept asking who was calling and she kept saying Yolanda.
(i was trying to determine the company she was calling from) so rude. eventually after 5 t imes of who's calling? yolanda. calling from where? are you the owner?....
eventually she said she was calling from ats merchant services. or something like that.
i hung up.  like i would ever consider dealing with a company so rude when there is no problem!
what would happen if a problem happened? and they want me to trust them with my money?
have people gone mad?

Did some research - that number is a pay phone located at Toronto Bus Depot.
You can hear the bus announcements going on in the background.

They keep calling 20 times / 2 weeks

Any idea who could call from this phone number.

Guy called Sean called about "Merchant Services". Pushy, told me they were sending someone out to meet and go over rates the following day. I told him I wasn't interested and he just kept talking so I hung up on him.

OMG, They are beyond rude. a black lady called me and after I wasn't interested in their scammy services, she told me I am being stupid and how good the opportunity is and how I have no business sense and should just quit and work at mcdonalds.
Very unprofessional!
