Form no 16

1. I was appointed in company A which is PVT LTD Company  ( due to this copy of My CV and my experience certificates are with (A)

2. My services are terminated by A and they have appointed me in Company B  

3.Company B is also PVT LTD company and wholly owned by Company A

4.Company A and Company B both are PVT LTD companies with Separate PAN NO,TAN NO,PF NO 

5.Company A is using my CV and Experience Certificates in various GOVT projects and  claiming reimbursements my salary as if I am employee of Company A and paying this salary to me directly from the bank account of Company A (without crediting this money to B Company account and then B company to me)

7.Though my salary is paid from Company A bank account directly, Company B issues me Form No 16 and My PF is deducted and credited by Company B.

8.Company A has never issued me form No 16 nor TDS is deducted by Company A

Now my query is

1. Paying salary directly from the bank Account of company A  to the employee of B  is as per tax laws? 

2. I have not paid any salary by company B from its own bank account  for last one and half year and still company B is giving me form 16 deducting tax at source

is this practices of company A and Company B  is correct as per IT laws?

Can I insist company A for issuing form No 16 / Form no 16A for the payment made? if not given by company A then how to tackle this with help of IT department.
