Tax sale house is being sold in foreclosure

[Devon Daniels]

I bought a house during last years tax sale in ALABAMA that was owned by a mortgage/debt company. I took possession of it after I got the tax certificate and have paid this years taxes.I also sent the mortgage company a letter informing them their house was bought during the tax sale. 

Months later I was looking at foreclosures in the area and to my Surprise , the house is going for a foreclosure auction at the courthouse in about a week. What should I do? Call the Lawyer who is handling the auction? Call my lawyer?
