Brother International Corporation Ignores Customers and Gives Them the Run Around When their Defective Machines Break Lansing, Nationwide

I have had nothing but problems with my Brother MFC-9840CDW printer every since I bought it about two years ago.  I have been fighting with Brother since that time on it.  When I try to make a copy, it often will not let me because it thinks it's receiving a fax even though there has never been a phone line hooked up to it.  I have to turn it off and back
on and quickly make copies before it thinks a fax is coming in again. 
This has been going on the full two years.  The fax settings are on manual receive so this shouldn't even be an issue.  I tried to go into the fax settings again though last weekend, but it just beeps at me if I try.  I faxed Brother a year ago about it, but they completely ignored my fax. 

Starting last weekend, I also cannot print or make a copy at all.  It will just beep at me.

I also complained to Brother tech support about the unit printing 3 dots along every page.  The agent said he would contact me again the next day but he never did.  I tried calling Brother back on the weekend but their tech support team that the team that covers my unit isn't available on the weekends.

I finally e-mailed Brother and demanded either a refund or a unit replacement.  A rep from Brother called me.  I called him back two different days and left a voice mail each time.  On the last voice mail, I told him to e-mail me instructions to swap this unit out for a new unit.  Today, on 8/2, Joe e-mailed me, but did not include any instructions on exchanging the unit.  Joe claimed that I have not replied to his messages.  That is false.  I called him back and left him voice mails
twice.  I am not sure why he is lying about that.  I replied back to him with what time I am available for him to call me, but the e-mail bounced!  I forwarded the e-mail to Brother customer service at custsrv@brother.com, but that bounced
too!

I also had to fight with Brother for weeks to get them to send me a Windows 7 installation CD.  I dont understand all the hassle for such a small issue.

Brother had the nerve to e-mail me again today saying that I needed to cooperate with them and call the rep back whos been leaving me messages.  I have been calling him back!

Since it is impossible to get a hold of Brother and since this has been going on for two years, Brother needs to just send me a $570 refund.  I no longer want a replacement.  I'll buy an HP printer.
