Myntra.com — account locked without reason

Address:

Indore, Madhya Pradesh, 452018

I am having mantra account since more than 2 years and on 4th of jan i placed order for 7-8 shoes pair and which was received by me on 15-16th jan, after received of order found that some of shoes was not fit to me and then i was trying to open my account for exchange and return and i found that my account has been locked then i have called to customer care & they were inform me that concern person will call you in 24 hrs but no one has called me since 24 th jan. On 24 th jan i have received email that your account has been locked and can not reactivate and can't refund or return products from this account you may read terms o[censored]se from our website clause. Really it was very much surprising to me because i was going to exchange and return my unused products due to oversize and understand my account has been suspend without any reason and now i can not return or exchange my products worth of more than rs 8000.. Please advice me what can i do now because understand account has been locked intensionally by myntra to customer can't return or replace products.
