I am trying to get word to merge this info in and I'm tearing my hair out with it

I have a csv file that looks something like this

customeraddress1,customeraddress2,customeraddress3,customeraddress4,invoiceline,invoiceitem,invoiceprice,invoiceqt
et
et
et

So, this is what I want to do

<<customeraddress1>><<customeraddress2>><<customeraddress3>><<customeraddress4>

** repea
<<invoiceline>> | <<invoiceitem>> | <<invoiceprice>> | <<invoiceqty>><<next record>
** until lastrecor

where the ** bits are things you don't appear to be able to do. This would give you an output of

10 Blah bla
blah de bla
bling blin
Bloomsvill

1 | Headache | £10.50 |
2 | Baldness | £100.20 |
3 | Eyestrain | £50.10 |
et
et

You get the idea? There doesn't appear to be a way of doing this. If someone could help I'd really appreciate it
