Who called from 5033454298

Calls one time everyday and does not leave a message.

Same with me, I have so ar received 2 calls at the same time with no message.  I do not know who it is.

frequent calls no message - called back and was allowed to remove my number from their customer service

I recieved a call form this number and several others today (about 5 total) they all didnt leave a message and when I returned their call, I was instructed to enter in my phone number to be removed from their calling list. I did not for fear it would enroll me in some sort of automated mailing system or somehting of that manner.  My phone says the cal originated from Portland, OR

did it stop the calls?? and were there any side effects to you entering in your phone number? as in did you get more calls or something of that nature.
