The number starts to join on a list to call me every day. The combination of the numbers on the list have been calling me every day for quite a while.
Week ago, I called back once on one of their numbers and selected sales option in order to get answered by a human.
The guy answered the phone told me that the company name is Dr. Green.
I asked him please stop calling me, he asked me my number and name and how long I have my number. Then he said the reason they are calling my number is that the previous holder owes them money. After I explained that I was not the person. Then this is what he said: "If you are not the person, then don't worry about it. But we'll keep calling the number." What an assh01e!!!
Not only that, they start to use more different numbers to call me everyday. The lucky thing is that my cell phone has a nice reject list function. The number on the reject list will not ring but just display as missing call instead. When I get a strange number, I just put it on my reject list.
So far, I have the following numbers on my reject list. They are ALL from the same company. The whole bunch of jerks:
1-+1 877-374-7336
(519) 618-1148
(519) 618-1149
(519) 629-6400
(905) 625-4065
(403) 444-3033
(403) 536-6772
(403) 910-0435
... and growing ...
(905) 625-1223
I am sure the list will keep growing fast after they read this.

Calls every day at 15:00.  No message and no one on the line.  Have had phone calls from Wells Fargo before for previous tenant.  Would also go with urine option below.

To Message from "MR" that I think is affiliated with "DR" company
A good reason since I got that phone not for people like you to call me whenever you wish and more so that you do not answer. It is that simple. Not sure you get it. I personally never buy any thing from anybode that calls me over the phone let alone if they wake me up.
