Pathetic Service - DTSV ******

I'm very unhappy with DSTV and the way my query was handled the previous consultant managed to assist me halfway, but no one can explain why should I be billed R899.00 instead of the initial amount agreed on for R809.00 which included extra view and show max without any additional charge. The credit adjusted of R645.00 doesn't make sense at all which should have been R1440.00 since I was incorrectly debited from July 2019 until now. I need someone Senior or the initial sales consultant that contacted me previously to assist as he was professional and understand what is customer excellence to get the matter resolved timeously.
