Myntra.com — Not able to use my myntra credits

While creating myntra account my email id was wrongly typed. Due to this I was not able to place the orders as otp was going to wrong email id. I called the myntra multiple times but they told that email update is not possible, even otp redirection towards register email id is not possible, and even someone asked me to contact google. They told silly reasons, I called multiple times but no use. Even they locked my account. They are saying silly reasons but no action was taken after 10 days . Whenever I call and raise the request/incident telling the issue, they simply saying within 2 days they are going to acknowledge it but not the action. Even i was disabled to write my queries in the app to. I got too much mental stress due to it.
