Vodacom ows us R29 520.70 for 6 months allready

I PORTED 10 NASHUA MOBILE NUMBERS TO VODACOM ON A BUYOUT DEAL AT THE END OF JULY 2014 THAT WAS APPROVED BEFORE THE RESTRICTION TO PORT NUMBERS WAS PUT IN TO PLACE. THE APPROVED BUYOUT AMOUNT WAS R29 520.70 WHICH I WAS FISRTLY TOLD THAT THE AMOUNT WOULD BE PAID OUT TO NASHUA MOBILE, BUT WE WHERE THEN INVOICED FOR THE FULL BUYOUT AMOUNT FROM NASHUA MOBILE. AFTER FOLLOWING UP WITH VODACOM, I WAS THEN TOLD THAT I HAVE TO APPLY TO BECOME A SUPPLIER, AND ONCE APPROVED I MUST THEN INVOICE VODACOM FOR THE AMOUNT AND ONLY THEN WILL WE BE PAID OUT FOR THE R29 520.70. SEEING THAT I HAD NO OTHER CHOICE I DID ALL THAT END OF SEPTEMBER LAST YEAR AND NOTHING HAPPENED. I STARTED THE WHOLE ENQUIRY OVER AGAIN THIS YEAR, AS DESRIE ROUX IS ON MATERNITY LEAVE AND BUSI DLAMINI NOW REQUESTED ALL THE DOCUMENTS AGAIN, WHICH I SENT TO HER THE 28TH OF JANUARY 2015. A FULL WEEK LATER SHE THEN SENT ME THE SAME DOCUMENTS THAT I WAS INSTRUCTED TO COMPLETE LAST YEAR, AND WHICH I SENT HER ON THE 28TH OF JANUARY, AND ASKED ME TO APPLY FOR SUPPLIER APPROVAL ALL OVER AGAIN. THIS IS SUCH A RUN AROUND AND IT SEEMS THAT WE WILL NEVER GET OUR MONEY FROM VODACOM, BUT I REFUSE TO JUST LET IT BE.
