Urbanic — Refund purpose

I have ordered a sweater from urbanic and when i got the product the material was too terrible. so i return the day after itself and the pick up of the product was also very fast. But when i ask for the refund they first told that it will take 7-10 days but after 10 days also i didnt got the refund so i enquired with them so they told the bank details are incorrect which is a false statement because am a working women and i am getting pais to the bank acount that i given urbanic also. whatever it may be so i changed the bank acount and give another bank acount details to them but then also no responce from them. its been 25 days still i dont get the refund. when i complaint them through the customer care they are still telling like refund will be processed within 7-10 which is bot text from thier side. so i contacted them throgh tbeir mail, they are not even responding to the mail.
