Amazon India — Product not delivered after placing order

Hi,
We have ordered LENOVO TAB on JUNE 21st, till now item not yet delivered. We have called to Amazon customer care about delivery but they said initiate refund and some other reasons. If we want re order the item also not available and sometimes price is also very high.
They are cheating the customers after placing order. Many times called to them but even one time also not given proper response through email/sms.
We need the item immediately or pay the double amount since they have wasted our valueable time. Please take the action on Amazon India immediately.
