If you were an electrician, you would understand the concept of a circuit.
If you want to supply a load from a circuit, you get the live and neutral from a single circuit.
I suggest you look in the wiki, or get yourself a copy of an electrical installation book. Ideally, get yourself on an 2330 course, before you do some real damage.
Assuming this is in a kitchen or bathroom, this is notifiable. Read up on Part-P.
Don't blame your customer for this. He wanted the job done. If you have done as you stated, rip it out and do it properly.
