I believe the chat option is the best. Have a script made up that you can copy and paste into the chat window. Hi, my name, account number, phone number.....I am in my RV and I have relocated to the following address temporarily. Please change my SERVICE ADDRESS ONLY to the above address. My billing address remains the same. Thank you.
If chat is not available and you need to talk to someone ask for technical support. If you get a "Spanglish" speaking rep. that you cannot understand or does not understand you, tell them that you need to be transferred to a US based support rep.
