Very disappointed

<div>Dtsv they have blocked my decoder saying that I owe them an upgrade amount which I didn't do any upgrade I last did one last year been speaking 6 different consultants since Morning even now haven't been helped this is ***** cos I paid R380 which I pay R350 every month I since had this account since 2013 never was I left behind with payments have proof of payments of every month and also never did not pay my installment so what annoys me is that they saying I owe them and I don't now can't watch my TV whilst I paid</div>
