Pathetic customer service

MULTICHOICE has been charging me extra for a decoder I didn’t have. I complained on the 28th January 2023 at their walk-in center (after noticing that something was wrong with my bill )with a promise of getting a refund to date no refund received. As follow up on my Query I phoned customer care on numerous occasions and spoke to the ff; people 2/2/2023 spoke to Yerusha *** . 9/2/2023 Sindy @17h15 ref: I 878 24/2/2023 Joy *** 21/2/2023 Cynthia ref: I 925 1/3/2023 Masithole ref: I 929 3/3/2023 Zanele ref: I 933 All of them escalated the refund query to date with no money reflecting in my account after being promised the refund takes 5-10 working days to crown it all the refund amount is now reduced by R648.00 from what was supposed to be refunded. The agreement was that they refund me and continue with the usual debit order . This refund amount backdates to August 2021, this is March 2023 . It takes MULTICHOICE more than a month to refund customers 👀☝️but takes them 24th hrs to suspend your viewing wow what a service
