Unauthorised changes to my Package

I've just gone on to VODACOM website to review my bill and got the SHOCK OF MY LIFE.<br> <br> <br> <br> on Cellular 082***XX42 I'm being billed for An OPEN DATA LINE.<br> <br> I HAVE NOT SIGNED FOR AN OPEN LINE, I TOOK AN 2GB TOP-UP PACKAGE.<br> <br> I HAVE NEVER GIVEN PERMISSION TO HAVE THIS LINE CHANGED TO AN OPEN LINE, I have queried on the cost to migrate to a 5GB TOP-UP, AND WAS TOLD THAT I'VE GOT AN OPEN LINE, AND CANNOT CHANGE.<br> <br> I THOUGHT THE AGENT WAS JOKING, AS SHE WAS HAVING SYSTEM PROBLEMS WHEN WE SPOKE TO HER. ACCORDING TO THE AGENT MY CONTRACT HAS ALWAYS BEEN FOR AN OPEN LINE - bull sh!!!<br> <br> <br> ON Invoice B986****** I'm being billed for Content services - WHAT THE HELL IS THIS FOR.<br> <br> <br> IF THIS PACKAGE IS NOT CHANGED BACK TO TOP-UP IMMEDIATLY, AND ALL THE ADDITIONAL CHARGES NOT REVERESED, I WILL TAKE THE MATTER FURTHER.<br> <br> <br> <br> <br>
