Need 4 Coldplay Tickets (together) for 21st Jan Mumbai at close to SP

As title says, I am looking for 4 tickets together for Coldplay on 21st Mumbai at Selling Price or close to Selling Price. DM or comment if interested.

Prefer F2F in Mumbai/Delhi (NCR)

Optional: I dont want Ahmedabad ticket as I already have extra Coldplay tickets for 26th Ahmedabad. Travelling is not possible for me so planning to sell that off.
