My services are being suspended for No reason at all

Multichoice keeps on suspending my services even though I paid my account in full and on due date , which was the 15/09/2018. Since from the 15th they disconnected me 3 times reason is that my payment is not reflecting . I mean for heavens sake I paid my account on fnb cell phone banking , and I forwarded proof of payment to Multichoice . some one is not doing their job and that's makes me suffer for that . already I spent over R100 on airtime and data trying to contact them in vain . Shame on you Multichoice
