Lack of information

Please urgently assist me. I have tried contacting your call centre but unfortunately they do not have the information I require. My contact for uncapped lte ends 27/2/18

I do not want to renew it or cancel it. I want to continue on the same terms, obviously at a lower rate as the device would have been paid off, on a month to month basis. Please advise the way forward. Please also advise what happens if do not give notice or upgrade.

Thanks
