Apple India — Misconduct and Not Value for money

Address: Kolkata, West Bengal, 700008

Website: Apple I phone

Hi,
Please note that I bought one iphone 7 plus from your store outlet at Acropolis Mall Kolkata on 4th Feb'2017 but unfortunately I have had a very bad experience and am utterly dissatisfied with this purchase as I am deeply regretting my decision to buy this article from your said store. Reasons for dissatisfaction is briefly described below.
1) The said phone is purchase in exchange of my iphone 6 plus which is close to two years old.
2) Though my previously purchased iphone 6 plus is in very good working condition, salvage value declared by your concern store manager for the said iphone 6 plus was merely Rs.7200/- which is almost negligible.
3) Whilst swiping the Credit card I was offered 0% interest EMI, and I was told that effective EMI will be amounting to Rs.3416/- for 24 Months considering the down payment of Rs.10000/- but surprisingly I found that EMI charged post swiping of Credit Card is Rs.3976/- P.M. which means an approx ROI of 16.4% P.A has been charged hence not acceptable at all!!
4) Before purchase I was told that all the data of my previous phone will be transferred verbatim but unfortunately post purchase I lost all my data pertaining to "Exchange Mail Folder", your store manager reluctantly informed that he is helpless and can't do anything about it
5) As it was little late in the evening everyone out there in your store was in a hurry to go home rather than attending a customer. I appreciate everyone's time, but they should have estimated the time before accepting the transaction and should have acted accordingly. Instead of sending me a message of "Depriving"
6) As soon as a I came out of your store that evening, I realize that I should retain my old handset and immediately I tried to call your store manager on his mobile but he didn't pick my call (fact of the matter is I called him number of occasions but didn't get any response nor he bother to give me a ring back on the following day)
7) Since there was no response, I dropped a message expressing my intent to take back my old set. Following day morning I called up your store and spoke with number of people who assured me that they will initiate a mail and as 5th Feb'17 was a Sunday there are chances that I can get it back. They also promised to keep me in loop for such communication and since then I have been following up aggressively but so far I didn't receive any positive response from your end neither I receive any copy of the said email.
8) Perhaps first time I have such unpleasant experience with Apple!!!
9) Your immediate corrective actions will be highly appreciated.
10) You are also requested to arrange immediate cash back!!
