Callsign required to change to M0JXR from ZS5BG sysop

It has been a frustrating while trying to get the callsign I had running as a sysop migrated over to my new call M0JXR.

There are no hf servers in UK and want to run one but have had no response from the few email addresses on winlink .

This is very frustrating .

Anyone have alternate contacts who can assist in transferring access from old call to new one .

thanks in advance
