Amazon India — Account has been hold

Address:	Dehradun, Uttarakhand, 248007
Website:	Amazon.in

My name is Sahil Rawat, my registered ID on Amazon is [protected]@gmail.com and phone no [protected]. They have put my acc on hold and saying that to confirm visa credit card ending with 54. I don't have any visa credit card as I only use master debit card for shopping on Amazon. I don't know why there are demanding to verify that visa credit card as I only have master card and also m not having any card which is ending with 54. I m ordering something but they are canceling it saying that verify that card first. I have mailed [protected]@amazon.in, [protected]@amazon.in, [protected]@amazon.in but no one is responding to my mails. I also called customer care but they are also not able to help me. I have 4k rs in my amazon wallet also. Plz help me.
