Complaint Regarding Contract Cancellation, Activation & Affordability Concerns

I defaulted on my payments for two months, but I rectified my account in August 2025. Following this, I requested for my contract to be cancelled. However, the service consultant advised that cancellation is not possible as the contract must continue. This has caused confusion, as I was under the impression that my contract had reached its 24-month term. Additionally, despite settling my account, my SIM/account has not yet been activated, and I have not received any explanation for the delay.

I would appreciate clarity on the following:

Why has my account not been activated despite payment being made? When will I be eligible to cancel or downgrade my contract, as the current plan is no longer affordable for me? Confirmation of my contract duration and end date.
