Telus anniversary sales are unviewable/unusable

When I try to view the mobility deals I get an error on any browser I try to use.  Then when I try to get chat support to help it gives me this error.

I get very frustrated with the Telus web site constantly giving me errors when I try to use it making it unusable - but to avoid fees you need to use the web site to get services.  

Does anyone else have this problem?  Is there any way to get this website to actually be usable to get services or services changed?  It almost always errors me out when I try to use it.
