HI guys, can someone help me with this:

I own two companies and now,
I'm buying a recond estima for company B, selling the alza for company A
But I want the number of Alza to be transfered to the new estima.

How can i do that? the seller of Estima just tell me *cannot do* end of story..... which I think he is just simply ignoring my request.

thank you all in advance.

My alza still under loan but a bit only, can settle anytime. I'm not in urgent to sell the alza at the moment too but i really hope the number can be remained
