Item not as described and pictured

[pommiejack]

I purchased a computer charger.  The picture and description states 8 piece connectors and power cable that were not in the package.

They seller did say to contact him if I had any problem to which I did reply about the missing items. 

He had said he would give me 30% refund.  I really should get the 100% refund because without the adapter it is no good to me at all.

My question is

For the sake of my fellow ebayer should I open a dispute because it will force the seller to take off the item and correct his listing so other ebayer do not get stung like I have, or do I just get my refund and seller keeps on duping others.

If I do nothing seller is making a small profit on useless items.

yes, open a dispute
