SABC ABSOLUTELY USELESS REGARDING REFUNDS

Good day I paid my Tv license twice by mistake in November 2018. I contacted the SABC to get a guideline on how I can go about getting a refund. They said a refund will take 4 weeks. (How craze but they quick to take the money when payment gets made) I gathered all the required documents and sent it through on the 28 November 2018. they then advised that they need my full set of bank statements for my account details and proof on my bank statements that i paid twice. I then sent the documents in again on the 6th December 2018 when i received my monthly emailed statements. I sent a follow up email no response. I sent the documents again on the 7 January no response. Please can someone contact me urgently regarding this refund??? Before posting this complaint I sent the mail 5 times hopefully someone takes note of it. Its been 2 months. This is absolutely ridiculous.
