Shop Clues — problem in returning items

Address:

Darjeeling, West Bengal

I had order a number of items from shop clues and have found a lot of them defective and of poor quality.So i had requested for a return and refund.After a couple of days two items are showing that the return period has expired and two other items cannot be picked up from my location. please look into this matter and do resolve it as i have already paid for these items.
