On moving to BT, my elderly, hard-of-hearing grandparent intended to retain our phone number, but this did not happen (whether through misunderstanding or miscommunication). We were only made aware of this months later when our original number was deprecated by our previous provider, and we contacted BT to inquire what was happening. We're now outside of the period BT would allow us to reclaim our original number. The problem is that BT did NOT notify us of the change of phone number. Had they done so, we would have been able to promptly rectify whatever issue led to not retaining our original number, and we would have been able to reclaim our original number within the allowed time period. The agents I've spoken to have been nothing but helpful, I cannot fault them and I understand there's nothing further they can do to help, but the failings of BT's processes have resulted in an easily avoidable issue and inconvenienced my elderly grandparent.
