*Akon is not backing down from a construction company who is suing him over an unpaid bill.

Jay Poorak, who runs Southern Electric, has sued the star over claims he failed to settle a $51,000 bill for renovations on his Georgia mansion.

The singer has just filed a countersuit, alleging he was overcharged for poor workmanship. He claims much of the work on his home was carried out without his permission and without a price agreement.

He also claims the work was a disaster and he was charged $150,000 for a job which was only worth $33,660, according to TMZ.

The singer is suing to regain some of the money he has already paid and for damages from allegations of slander.
