Servpro Construction on house after tornado Dallas, Georgia

I had a tornado come through on April 27 of 2010. Servpro came in 2 days after. they told me they would work off my ins. and it would not cost me anymore. I signed up for construction and emergy servs. I paid for the emergy serv. then they hired a contractor who hired a sub-contractor. servpro told me the job would take 2 and a half to 3 weeks to do. the sub-contractor that they hired to do the job,he was on drugs and cut materials and never had enough materials to do job. the job took about  3 months to do. he hired guys off the street to do one job at a time and I had at least 5 or 6 different people come in to do a job one at a time. this is not a crew of sub-contractors that should come in of 5 or more and be knowledged in their job. I paid them almost all of my insurance check. now that everything is done they are trying to get even more money from me. I tried to call their construction manager named Michelle George who was very rude and very unprofessional and when I tried to talk to her she hung up on me. they are trying to file a claim on me through a lawyer. Public BEWARE!!! before you consider using servpro you might also be taken in by them.
