What to Write in a Service Provider Contract Termination Letter

Dear Customer Services,

Concerning Mobile Phone number: 0990-9484-393

Customer number: LSF00-21

I recently visited my local (Orange) mobile phone store where they confirmed to me that I am no longer bound to my (12/24) month contract which ended on (day/month/year).

I would like to formally cancel my long-term commitment with (Orange) on the current monthly contract, and my and am hereby giving my (30/60) day notice.

I would however like to port my telephone number over to a Pay As You go tariff with (Orange etc.) and would like to know how best to proceed.

I await your positive response and advice as soon as possible.

Sincerely,

(Name)
