SABC TV Licences Bad

I got my account up to date 14 Dec 2018. Now they have billed me again with R927.00 which is impossible as there annual fees is R265.00 a year. So it cant be more than R530. I have asked them for a statement which can reflect my payments and up to date bills. Instead they threaten a person with an amount which is totally unacceptable. I wish they can get there stuff up to date. They even sent this letter on old *.doc format, and not responding to my query.
