Changing selfservice login email address impossible, address update disaster

I log into the selfservice website to update my email address. Site looks pretty. Then I go to update my details, put in my new email address and click next. Here it wants my address again, but the dropdown menus don't have all the info. Same with the postal address, it is impossible to put a Postnet postal address on there. Why all the fancy dropdowns? Why not give us the option to just enter an address!!!! Ok, so after all that I find that it only changed my email address on the contact page, not my DSTV connect email address. I find the place to do that, but then get an error and I should try again later...I just want to update my email address that I use to log in. Why is this such a mission???!!!!!
