Price Lock

I have most probably logged 6 queries with DSTV and each day it get escalated to some where as I never get feedback. I signed up for price lock and to up the explorer that was installed 19th August 2022. A week later I get an invoice that I owe them over a thousand Rand with so much charges added that no one can answer to. Like WTH is happening with MultiChoice I need answers and my account adjusted this is madness !!!!!
