Disappointed

I called dstv contact center to downgrade my subscription on the 5th of this month from compact plus to compact. Was then given a amount to pay to re-connect my services because I had missed my normal pay date (31st) so I was given a amount to pay (pro-rata) I then paid and emailed my proof of pay. Then my services were re connected. Today I'm disconnected and I'm told I owe. Called a countless times to resolve the matter but to no success.
