False advertising and misleading consumer's daily

We bought a new recorder with a promotion of 1 month access to Dstv compact on the 28 January. We were billed almost R80 which we paid. Now Dstv has disconnected our services saying we must pay almost R500. When you contact them their consultants give inconsistent and misleading statements. Y'all are ****** and misleading and false advertising seem to be a thing for you
