Unhappy Customer for the 2nd time

Vodacom Service is beyond unprofessional, its my second time now coming to this platform for them. How can you change the rules on the contract I have with you and not even have the audacity to inform me. luckily I always check my statement. Apparently, I now need to pay for data on the 2nd useless sim card that I was told comes with the contract. To my surprise now I must pay for it.

Please know this...I will not pay for that. my contract is for R189 not R266 any payment taken from my account without my permission that's ***** and I will direct it to the right department.

AGAIN I DO NOT MIND CANCELLING THIS CONTRACT AS ITS THE PAIN UP MY .............................. Please resolve this: ***
