MISLEADING AND BAD SERVICE

I HAD A DATA CONTRACT WITH 8TA AND WAS PAYING R199.00 A MONTH FOR TWENTY FOUR MONTHS. I GOT CALL FROM AN AGENT FROM SELLDIRECT. THE AGENT TOLD ME THAT MY 8TA CONTRACT HAD EXPIRED AND ON BEHALF OF TELKOM THEY ARE OFFERING A BETTER CONTRACT. ONCE HE TOLD ME A INCREASE PRICE I REJECTED IT. HOWEVER HE SETTLED FOR THE PRICE OF R199.00 PER MONTH FOR A 5GB DAYTIME DATA WITH OVERNIGHT DATA WHICH I DONT REMEMBER HOW MUCH. I AGREED BUT NOW I GET AN INVOICE OF R279.00 INSTEAD OF R199.00. I AM NOT PREPARED TO PAY 279.00 AS I WAS HAPPY WITH MY CONTRACT (MONTH TO MONTH USING MY SIM CARD ON A ****LE). THE DELIVERY NOTE FROM SELLDIRECT DOES NOT HAVE ANY CONTACT NUMBER ONLY MY DETAILS AND ACCOUNT NUMBER. THIS IS DAYLIGHT ROBBURY AND SELLDIRECT IS TAKING CUSTOMERS FOR GRANTED. I GOOGLED THEIR WEBSITE AND THEY HAVE A NUMBER AS *** WHICH DOES NOT EVEN RING. IT JUST DEAD...ARE THESE SELLDIRECT PEOPLE THINK THAT WE ARE IDIOTS OR WHAT? I WOULD LIKE THEM TO CONTACT ME TO CANCEL THIS '****'. I AM CONTACTING TELKOM TO COMPLAINT ABOUT TH IS BEHAVIOUR FROM SELLDIRECT. HELLOPETER IS MY ONLY HOPE AGAINST MISLEADING BUSINESSES LIKE SELLDIRECT
