Mobland Subtitles incorrect

My husband and I are watching Mobland on DSTV Catch-up. The subtitles do not correspond with what is said at all. How is this possible? DSTV should look at other Channels to see how it's done, or rather not offer subtitles. I've never seen anything like it. It actually spoils the show for me. No wonder I hardly ever watch any shows on DSTV. Unlike other channels, DSTV is very expensive as well. Definitely not value for money.
