Xfinity Movers Edge Seamless?? Let's explore

Question

Please be aware that xfinity’s Movers Edge service does not work.  As a result and after sticking with the company since 2002, I will be taking my internet/tv business elsewhere…anywhere else. Where to begin?  First of all, the program sells how easy and seamless it is.  To me, seamless does not include me being without service for 20 days.  20 days!  I work from home.  How am I supposed to accept that?  “Oh, we’re busy.”  Well, I don’t think it’s too much to ask to have enough staff to cover demand.  The way I see it, their view is that new customers are more important than retaining existing customers.  That’s bad for business.   Secondly, this was after xfinity/Comcast tells me they will call me to finish setting-up the transfer for the date requested.  They did not call.  I only move the process forward by calling back several days later.  The new rep is not even able to acknowledge that my move request was a call back.  I’m quickly told that I can self-install that can work for me but later in the call I find out that no, really they have to send out a tech…but no tech is available for 20 days.  So the program is neither seamless nor easy. Oh, it gets worse.  I’m told, let’s just put in the transfer and you can call the local office to see if they may have cancelations.  I don‘t like the idea but agree.  The next day, I call the number given to me and I get a general Comcast message saying the number does not work.  You must be kidding me.  I ask Google to be sure I didn’t transpose the digit.  Sure enough, I dialed the right number and it doesn’t work.  Come on. There are many other internet and TV options out there competing with xfinity/Comcast.  After 15 min of quick research, I decide to cancel my service.  I call to cancel.  Retention says, “We’re busy.  The next available transfer/install date is the same 20 days later than my move date.”  Well, that wraps it up.  My business is not important to them.  It is not hard to find a new partner.  So in a nutshell, xfinity needs to say that the move program works if you give 3-6 months’ notice of a move.  Maybe then they’ll be able to find a tech to assist because you likely won’t be able to self-install anyway.  Oh yeah, for the longtime customers, xfinity appreciates your loyalty, but their loyalty?…draw your own conclusion.  xfinity, you have to do better. 

Answer 1

I did create 100x100px rectangle at 0x0px. Then I exported that to tiff with anti aliasing on (composition, or whatever it's called in English. Unfortunately changing language in Illustrator is not that easy. Anyway not text anti aliasing).
Problem still exists.
(here is ai file: rectangle.ai)
after export gives:
exported_rectangle.tif
So I believe what you suggested is not an issue.
Edit:
Just to make sure I did export it with text anti aliasing on as well. Effect is the same. I used following export settings:
Color model - RGB
Resolution - 300dpi
Anti aliasing - both as mentioned above
Compression LZA - checked
ICC profile - Adobe RGB (1998)
Edit 2:
Here is screenshot with transparency mask on. That proves there is no white background behind rectangle:
What's even more interesting, when I accidentally pressed Ctrl+C instead of Prt Scr to make print screen and pasted that to MS Paint, I've got exactly same thing as with export:
