Need help for PIO card

HI guys,

I'm Moroccan citizen who got married to an Indian I stay at Navi Mumbai, I want to apply for PIO card, I know all the documents required for that, I will tell you my concern.

1st when I sent to FRRO Navi Mumbai office to enquire about the place when I need to aplly for PIO they told me that  we are not responsible about the PIO you need to get all your information from FRRO Mumbai, when I went there they told me that, sorry you cant submit here as your a part of Navi Mumbai.

they said me that if you stay at Mumbai that you need to submit at FRRO Mumbai but you stay at Navi Mmbai you need to go to Delhi and apply.

I called up Delhi visa support they told me that you don't need to come over to apply you can send by courier all  the required documents and we will proceed, I asked them how long does it take to get the PIO card ? they told me it may take minimum 3 months. then I asked them if I send you the courier of my documents will you give me some CODE or Receipt or justification that I have send you the documents and its in process that will also allow me to follow up with you. they refused saying that it s not possible once your card will be ready will send it to you by courier.

I m having many doubt because no when in there web side its written that I can submit by courier....
Then I came to know that their is one foreigner who lives in my society I went to ask her she told me that it was very painful experience but she got it, she even told me that some of her friend applied but they didn't get replay and there document got lost ...

can anybody help me with solution when I need to apply should I go ahead and apply by courier? or if anyone had apply for PIO can guide me?

thanks,
