DSTV ****mers

I recieved a free 30 day subscription in December 2025 because I had not been using DSTV for a few months son in 2026 I wanted to reconnect and to my surprise, now im owing close to R1000 , I leave it and today I call the call center again now im told I owe R700 and something again I ask why and apparently its because of the free subscription I got in December im now in debt , what in the false advertising is this im so mad right now
