Poorvika Mobiles — Iphone Cashback and EMI

Address:

PLOT.NO.24, Amsaveni Complex, 87/5, Bypass Road, Rajalakshmi Nagar, Velachery, Chennai, Tamil Nadu 600042

Recently purchased Iphone from Poorvika online store after verifying the cashback from both customer service and a retail employee.It's been more than 30 days, so I contacted SBI bank, who informed me that the merchant had not shared your account information for the cashback winners list on the purchase. Since I made an online payment with a credit card and did not receive a receipt mentioning the cashback.
The Merchant has put credit card EMI for 6 months as he said EMI interest is 14% but it is more than 14% taking from my account.

@Poorvika, kindly assist to resolve and disburse the cashback amount and interest as soon as possible.
