Hi, i want to return a product. But email id is showing incorrect, but i used the same email id while ordering. Ivr is also not working properly. May i know how to return it, as there is 7 days within i have to return it. When i tried to log in with the same email id. It is showing not valid. When we are ordering its showing valid, while returning its showing not.
So kindly provide proper details where we can return.
