Hi,
This is Sathish from Salem . 29/08/21 evening I purchased an apple iPhone 12 mini silicone case white for Rs.4900/-.
Not even a day passed the color of the case turned yellow while charging through MagSafe wireless apple original charger . So I raised a complaint in apple store and went thr for a replacement ..at that time only I came to knw tat the product which I bought from poorvika is fake and the serial number in the case and in the box doesn’t match .. when I went to poorvika asking abt the issue they r not answering properly .. I need a refund ..now.. they r saying tat they don’t hav a sealed iPhone case and all r kinda diff serial number . They are asking me to purchase a different product Fr tat cost .. is this wat u people do selling fake products .. I need a resolution and I need a refund for this ….I purchased frm the store Poorvika mobiles, meyyanur byepass road, near arrs multiplex side, Salem -636004
