** It's sad that you have thoughts of removing one of your lines. I understand your concern and you can request it to be removed from your account. If in case you know someone interested in it, you can just transfer the ownership instead of canceling it.
** Cancelling a line is the last thing we want to hear from you, but we still respect your decision. No worries, you got me here now. Rest assured that I can certainly address your request. If you don't mind me asking, may I know the reason why you would like to cancel this line/account?
** Thank you for your patience. I was now able to cancel the line ending in (---) and it'll be effective on (start date) so you still have time to think if you wanted to still cancel the line and to lessen you hassle on contacting us to reactivate the line again in case.
