Account paid but suspended

I made a payment of R699 on the 11th of November 2015. 22:59:17 through Internet banking. I am surprised now that my DSTV was disconnected and I am told that I haven't paid my account for the month of December, even though you have debited my account on the 28th of November 2015. <br> <br> When I call the contact centre, I was told that someone made a mistake and used my account number. I am now accused of lying. I don't understand why they disconnected my DSTV without even bothering to check up with me if I made a payment or not because surely the payment reflected on their side. I even sent an email to that long email address but the email was rejected by their mail servers.<br> <br> This is terrible service.
