I was compelled by bank staff to apply for sbi card. Since receiving card have not activated or used card at all. I was billed AMC which is 500/- on card which kept compounding and deductions have reached 60000/- as on date. I have not received any bills regarding the same except in first few months after applying for the card.
I have not used the sbi card services even once, i am ready to pay the AMC charges which should not come more then a few thousand rupees. even after emailing to nodal officer i have not received any reply.
