I had ordered two shoes on 5th May 2017 from Clarks online website. The total amount of the order was 3800 INR after discount having order id: C[protected]. It has been already 7 days from the date of purchase but there has been no response or communication regarding the order status, the order stays undelivered. Please help me to find the order status and get the order delivered at the earliest else they should refund the entire amount to my credit card.
