Hi, my first post so please go easy.

I have a zgemma box in the UK, only basic channels currently working so no sky sports or BT sports, I tried to get a trial sorted for IPTV, the guy via remote attempted to do this via putty. However he said on the root my box has a password which I need to obtain.. he’s now disappeared.
Can anyone arrange for IPTV or recommend any viable options in this situation ? I mainly need sky sorts , bt sports , movies etc .
