Bad service

I had a bad service with dstv (multichoice).I paid the my account on time,while they billed me in correctly so they are saying I must wait for 7 days for their system to reflect that am not owing them,even though they see that I paid and I don't owe them.currently my decoder it's not active.

I ask to speak to supervisor,Langelo Mthebu the consultant told that they are not available,but when I insists,there was the team leader appears from no way Khanyisile Radebe,but still not able to assist.

I have paid for something that am not able to watch.
