Boat — Not able to Cancel the Order

I have ordered a Boat Rokerz 335 on 21st May 2021 through Boat official Website and paid online.

I want to cancel the order since 21st May but not able to see the option under Manage Order. Called the customer care and they told me to write a mail to [protected]@imaginemarketingindia.com by there is no repose.

Pathetic service from Boat. There is no Customer care details mentioned on the website, which is a very basic information.
Order No - 389522
