Un-blacklingg of a contract device

Dear Sir/Madam,

I am writing to formally raise a complaint regarding the delayed unblacklisting of my cellphone. I submitted the required documents from the 17 Sept 2025 and the latest was submitted on the 17 Oct 2025, refe#: *** and followed all procedures to have my device unblacklisted, but despite doing so, the phone is still showing as blacklisted. This issue has caused significant inconvenience, as I am unable to use the device as intended.

Could you please urgently investigate this matter and confirm the status of the unblacklisting process? I would also appreciate clear timelines on when this will be resolved. When I followed up, on 07-11-2025 I was told that your system shows that the device has been unblacklisted with this reference number *** and I was asked to resend the unblacklisting form as they are unable to reopen the service request that was closed.
