service address

I have been trying for the last 4 years to have my service address corrected. It should be the same as the billing address. I have talked to 9 people over the years and no one seems able to correct it.  The problem lies when they send replacement equipment... I never recieve it because it goes to a wrong address not even the same zip code.......Ive been with you folks for a long time. There is no need for this lack of attention.....
