DSTV Streaming package - unusable, but no refund forthcoming!

I paid the for DSTV streaming service via their website on evening of 6 July to find out that my Hisense TV is not compatible with this service. I reported this via the Whats App line on 7 June at 11:00, was promised a full refund of R 699.00 reference # INC-***. On 26 July I followed up again - as I had not been refunded. Supp**** copy of ID, bank statement etc - given new reference # INC ***. Still NO refund 9 weeks later! THIS IS DAYLIGHT *******, as I have not been able to use a product that I paid for and there is no way I can speak to anyone at DSTV to get some answers!
