Myntra.com — pickup done but not updated and myntra id is locked

Address: Vivek vihar colony house nbr 1 near goal girls hostel, Patna, Bihar, 801503

The courier boy came to pickup my product and he took the product away with him but in the evening i got the update that ur pickup has not been done .. so i called the courier boy then he told me that we have not updated the pickup because the pickup location is different from delivery location which is totally absurd.. few minutes later i was not able to login and a error message was being displayed on the screen that ur id has been locked ...
Now my 20000 rupees is pending with myntra and i want my refund as soon as possible
I haven't done anything wrong returned the same original product still they locked the id.. all i wnat is my refund as soon as possible
