Dell India — Regarding irresponsible behaviour

Dear sir,
To day i had place order for purchase of battery of my laptop insp 7348 tag 6hmpd32 after making discussion from the official of banglore. But after making payment rs 3800.00 i wanted to know the expected delivery of battery at my address then he told me that it will take 7 to 10 days. Then again wanted to confirmed that whether as per the discussion service engineer will install the battery in my laptop then he replied that no, engineer will visit only charge basis and there is no service centre of dell at ranchi. Sir i had never expected this type of cheating type deal from a international brand company. The very funny is that the different person were replying different ways of a single query. I became afraid that the battery may also be not genuine. As discussed from the first person and approaching up to last person it was concluded that they are doing dirty joke with me and irresponsible behaviour. If suitable immediate action is not taken then i will highlight this matter and may proceed for legal proceeding.
