[Resolved]  Eureka Forbes — Supplied product not working

I have complaint about not getting my valid paper of vacuumcleaner ( purchased in June'07 ) from Kharakpur center(West Midnapur, WeatBengal) .

My previous mail is coppied in the bracket :
(I purchased one vacuum cleaner from Mr. Jitendranath Mandol ( The C.S.S. of EUREKA FORBES at Haldia, east Midnapur).

On June'07 as two installment basis which has been cleared in 26th July'07 . Till now I did not get my valid paper. I told him two times ( Mobile No [protected]/[protected]) and also informed to his boss Mr. T Malakar ( At Kharakpur, west Midnapur) , but no action taken and I have not been informed about my paper' status. Mr. J. Mandol took Rs.300/- as advance also with two installment's cheques at the time of purchase which was illegal I came to know from Eureka Forbes service center and Karakpur center after two days . That time Mr. J. Mandol came to my house and returned Rs.300/- and also took apology for his mistake on pressure of Mr. T.Malaker and that time Mr. T.Malaker had assured me about no father mistake will be done in future by company. But again I am facing problem of not getting valid paper as my product has been facilitate for Maintenance free which is not possible with out valid paper.)
