It will cost you some, but at least they will do the necessary due diligence to get some answers, and try to correct the problems ..
The citizenship app is supposed to be a simpler process than PR, imo .. but sometimes when you find yourself in a tight spot, you have to seek help from professionals .. because clearly, anything you do is complicating things even more, due to lack of knowledge, information, and trying anything that comes to mind in a hurry without thinking ..
This goes for everyone - money comes and goes, so don't be cheap, and have the backbone to spend where you have to .. if you have to leave this planet tomorrow, you're not going to carry the money with you .. so use it to improve your life today ..
I've been reading a lot of people here making a mess of things because they don't want to spend money that could have saved them a lot of headaches .. common sense tells us that this forum is not gospel .. nobody here can tell you what to do, or how to fix your issues .. yes, they can guide you, but it's just a suggestion .. the ultimate decision will be yours and yours only ..
