So sorry ssekulji I only just got fully settled at the new place, having moved pc's and I cannot use discord on the mobile as it chews battery. It's past midnight here but I will take the time to reply now.

You can use steemconnect link to undelegate.

just put a zero in the amount you wish to delegate and use active private key to auth the tx.

The SP will take a week to return, or 5 days I think since last update.

Thanks for the delegation and it is unfortunate to see you go, sorry I had some issues with getting online lately as had to find a new place before finding time to post online.
