Aluminium rim theft from the basement

Hello, We broke into several cellars on 24.01.2008 in the apartment block. My Alufelgen OZ 215/40R16 with Dunlop Sp 9000 were stolen. Police took everything and I reported the damage of my household insurance (Alianz). Now after over a month nobody has reported to me yet, not even a letter that the case is being processed. Was with my representative and that we said still another week before we call directly at the Alianz and ask for . Now my question: is it normal that it takes so long for the insurance company to register? And above all, are my aluminium rims even covered in the household supplies? So can I expect to regulate the damage? Thank you very much.
