p1p, while you have a point, you're still at fault here.

You gave one week warranty, in which even on the last day itself, I found a tiny bit of problem and thus didn't want the item anymore, you have to take it back.

Or at least re-negotiate that you take it back, RMA then send it back to vick, or vicky RMA and you bear all the cost.

This is the risk you took when you give personal warranty, fair play that you didn't understand the concept of personal warranty, but we do, and from what we see, you lost on a business term.

And both are at fault here, so if one goes into the M.O list (dun think blacklist since there was no con involved here), so must the other.
