Applied for K-3 now I'm lost..help

[Jesus y Kipaima 0]

I filed a k-3 petition for my wife back in july days after we got married. Everything has gone fast for us, but now I am a bit confused, this is what happened: On September 15 I received a letter in the mail from NVC staying that they had sent a approved I-129F and a case to Ciudad Juarez; but a week later I receive a new letter again from NVC asking me to pay $70.00 for the affidavit of support form. What confuses me is that it has a different case number than the one I previously received. So I called NVC and say that the first case number was sento to Ciudad Juarez and that the second case number was for the I-130 form that I submitted along with the I-129F. So, I started doing some research I found out that I need to ignore future mail from NVC asking for fees. Is that true? Second, I called Ciudad Juarez and was told that my case was open and they would take 6-8 weeks to send package 1, and explained to me that the second case number I received was from the I-130 form and that it was for the process of obtaining the green card. They also explained that processing for K-3 or Green Card there in Ciudad Juarez took the same time to process. So, what do I do?

Do I ignore NVC and not send fee's payment?

Do I ignore Consulate and follow through with NVC?

Which is the safeties route?

BTW which is the cheaper way if any or at least the more reasonable and what would you advise to do and get approved on either one of the two choices that I seem to have since I (the petitioner) am currently unemployed? Hope you guys understand my post and can provide me with help. I am completely new and clueless of what I am doing, I am just following steps found at this forum for k-3 but after that I have no idea of what is happening. Please help!
