Hello,

I have ordered a lahenga online from this number +[protected].

Before purchasing i asked like they will return or not in message they told they will return.
After a week i m trying to message or call on the number there is no response of message and i called several timea but they are cutting the call instead of recieving and replying anything .

Could you please help me to return the clothes and refund my money 1850.

Please find some attached document of the proof and number from which order was placed.

Could you please help me to return the product and get my refund back and also i just want to say they need to response to the customer once they need any help after purchasing the product.
Please look into the matter and help me as soon as possible
