Sulekha.com — Deleting my account 2024

I just opened an account and I am deleting it due to the cost of posting an apartment. On the terms and conditions it reads "You can also close your account through this Platform by sending your request to [protected]@sulekha.net with your login email address. Your request will be processed within 7 business days. Your calls may be recorded to improve the service experience in the platform and for other business purposes." However when I emailed this email I got the error message that they are rejecting messages to that email address. "The response from the remote server was:
550 5.4.1 Recipient address rejected: Access denied. [PN1PEPF000062BA.INDPRD01.PROD.OUTLOOK.COM[protected]T20:42:21.259Z 08DC27D7A3DB9007]" I'd ;like to delete my account please. It should be easier and on the platform somewhere.
