Curtis, you're back! I think you're rewrite is more concise, making it easier to read.

If I understand this correctly, you paid Lowe's for an extended warranty on an air-conditioner that was returned to Samsung for service under the original warranty, but was never fixed, leaving you with nothing but an extended warranty, which is obviously useless because Samsung has not fixed or returned your air-conditioner.

That's interesting. I'm not sure what should be done in a case like this, but I do think you have the right to feel cheated. You paid for an air-conditioner and an extended warranty, and have nothing to show for it.

I think in the interest of customer service, Lowe's should intervene and try to help you out, one way or another.

Good luck with this and let us know what happens.
