Icy flyer had more luck than I had. But I think the fact that he had his BA number on Boarding Pass and he did it much faster than I did helped a lot.
I just got an answer from QRPC today at 2AM:
Dear Mr. -----,
Greetings from Privilege Club. We value your business.
We apologize for the delay caused in replying to you. We appreciate your patience.
We wish to inform you that we were working upon your request pertaining to removal of mileage for the flights commenced with our partner airlines.
Since the flights in question were flown in from April-2018 to 07-May-2018, we regret that we are unable to remove the same from your membership account.
We wish to inform you that we had verified possibility of mileage removal request; however, we were unable to remove the flights from your account due to the activities being older.
We apologize for the inconvenience caused to you due to this and appreciate your understanding in this matter.
We thank you for your cooperation in this matter is highly appreciated.
Sincerely,
Amitkumar Makhija
