Terrible attitude and passing the buck

On October 23 I opened Vodacom Contract at Sunninghill Village. The agreement was that the line was going to be capped at R50 upon data/ minutes allocation being exhausted. Suddenly yesterday December 24, I realized that data has exceeded with more than R700. These is despite the agreement being capped to R50. I called the call centre at once to seek clarity. Unfortunately, I was met with terrible attitude of the consultant who demanded proof that I requested the line to be capped at R50. I feel that this is unacceptable and ********* behavior from Vodacom.
