Handed over to attorneys after paying account.

I HAD MADE ARRANGEMENT WITH VODACOM TO PAY AN SET AMOUNT EVEYR MONTH. I HAVE HONOURED THAT PAYMENT. IN MARCH THIS YEAR I DECIDED TO PAY THE FINAL AMOUNT OUTSTANDING AS PER STATEMENT RECEIVED. APRIL 2015 I RECEIVED ANOTHER STATEMENT CONFIMRING THAT THE ACCOUNT WAS IN CREDIT BY R 2.62. TODAY 22/6/2015 I RECEIVED NOTICE FROM THERE ATTORNEYS THAT I NEED TO PAY R 1871 BY THE 2 JULY 2015. I HAVEN TO DATE RECEVIED A PHONE CALL /SMS OR EMIAL FROM VODACOM ADVISING ME THAT ANY AMOUNT IS STILL DUE TO THEM. WHEN DISCUSSINGTHIS WITH THEM THEY ARE UNABLE TO GIVE ME ANY DETAILS AS TO WHAT THIS IS FOR . I CONTACTED VODACOM AND THEY SAID THAT THE ACCOUNT IS HANDED OVER TO THERE ATTORNEYS AND THEY CANT GIVE ME ANY DETAILS. IT SEEMS VER CONVENIENT FOR THEM TO BE SATISFIED WITH THIS RESPONSE AND WE AS THE GENERAL PUBLIC JUST NEEDED TO PAY AND BE HAPPY. I WOULD CAUTION THE PUBLIC OF THIS AND RATHER STICK TO ANOTHER CELLPHONE SUBSCRIBER . YES I STILL AWAIT THERE RESPONSE, A PERSON WHO PAYS THEM EVERY MONTH ,THEN ALL OF A SUDDEN STOPS, SHOULDINT THE SUPPLIER PERHAPS QEUSTION THIS WITH THE INDIVIDUAL RATHER THAN PURSUING THE \NEXT"STEP OR IS THIS PERHAPS ANOTHER TACTIC TO SUCK MORE MONEY OUT OF US."""
