Technical Difficulties Updating My Email!?! Really?

My email address associated with my Dell.com account is incorrect after switching Internet providers.  I've tried several times just to update my email address.  I get the error message:

We're sorry, due to technical difficulties we are unable to process your request at this time. Please try again later. We apologize for any inconvience [sic] .

Really Dell, really?

When I've called to get assistance I'm sent on a wild call transfer ride.  Updating an email address is something really, really basic.  I won't mention the fact that I have to have several email/login accounts to access different parts of the Dell infrastructure (OK, I just mentioned it).  It just seems in the attempt to make the Dell phone/ordering/support system efficient they've created a rat's nest.

Does anyone know how to get an email updated on Dell.com?
