Still no response on previous complaint

I logged a complaint about bad service and overpricing repairs to my mobile device (which I got fixed in 24 hrs for R300 at a cell phone repair shop instead of R2800 that Samsung quoted, so don't tell me it really costs R2800 to repair my phone). I received a generic messsage from Samsung that they'll look into the complaint but never had any reply afterwards. Worst aftersale service in a ling time.
