Who called from 2125486166

No message left or anything. I live in Canada. Why am I getting calls from the US?

I do marketing for a restaurant and was trying out a site that does a punchcard program for our customers...it's called FLOK. I had to add my phone number to move further in the website and now I get two calls a day from this number...coincidence I think not! STOP CALLING ME

Calls repeatedly.  Have blocked but still gets through.
