Everything Is not Easy

Last month I received a letter from National Visa Center(NVC) about my mothers Visa application. We need to fill out form DS-230 to continue the process. To make it sure that she fill out all information right I only asked them if they can make a copy only on the page where she needs to sign. I only need her signature the rest live up to me.
I sent them the link and email them as well. I thought everything is all set they mailed me all the requirement's I needed like that signature, pass port size picture, birth certificate, NBI clearance, marriage contract until I receive all of this after 3 weeks of waiting. They printed text style instead of PDF. I make a copy and sent it to them right away I don't care how much it cost as long as I will get that signature ASAP. I sent it through FedEX last Friday and according to them my family will get it by Wednesday and guess how much it cost me just for that a piece of paper and a couple pictures? It cost me $58? If they can just get it right I will not going to spend that amount now once they will send it back to me I want them to send it through fed ex as well. I don't care again how much it will cost on my wallet. Ouch have to work part time soon.

Now hopefuly after a week or two I will be able to send that DS-230 to NVC. Hope from that point there will be no more issues. Good luck to me on that right?
