Consumer Redressal

I think perming.com is a fraud company. I have purchased a mobile phone using their online shopping web site (www.permingo.com). First the website said there is an option of cash on delivery but when I proceeded further to purchase the mobile, I was surprised; it said only advance payment option is available. So I made advance payment and completed the purchase, I got a mail in return confirming the order with payment details and also said the product will be delivered within 4 to 20 days, which is still not delivered even after the due date. Only once after 4th days, when I called the helpline number 9068600076 the representative has answer the call and explained why there is a delay in shipment, after that day onwards there was no one answer to the phone, no status, no mail replied, nothing
