Lack of feedback

I have made 4x payments to Multichoice for varying amounts on 05 and 06 January 2018. After three emails with proof of payments sent to some Boitumelo, Zakhele and supervisor Quintee at Multichoice between 6th to 8th of January 2018, I still have not received any feedback regarding the refund for a single premium that was paid three times!!!! There had been numerous calls I made to Multichoice's customer care regarding the matter and one consultant had mentioned that it takes 24 hours for funds/payments to reflect at Finance department. Now there has been so many 24 hours slots that have passed eversince the payments were made, and I am not getting any feedback from Multichoice whatsoever. I am getting impatient and annoyed with the lack of service I am experiencing with Multichoice, and it's absolutely unnecessarily unfair, totally unacceptable. I need the matter resolved URGENTLY
