HOW DIFFICULT is it to change my last name????

my 2 year anniversarry is on the 18th and I have been trying to have my last name changed on my child support order since
I have sent all the info they need 4 times and my checks still come in my maiden name
well now they have this new mastercard and not only did it come in my maiden name but it came to my old address and I havent lived there in over 4 years
everytime you call you have to wait on hold at least 20 minutes ....today I waited for 35 minutes on hold
there answer today was the same as usual we cant change it over teh phone and we will have someone call you

Thanks for letting me VENT

I'm changing mine tomorrow..6 months after the wedding. I'm going crazy with all this paperwork I have to do.
