Excessive data charges

After more than 20 years with Vodacom I have cancelled my two contracts. A sad moment for customer care and loyalty.<br> This is the complaint that finally broke the camel's back!<br> On the 27th November I received notification from Vodacom that my usage is extremely high and that it was in excess of R 5K (why only after R5k when my bill is consistently in the region of R1K.) I contacted the call centre and after a hard won fight I was put through to supervisor who logged a dispute on my behalf and sent me an 'itemised bill\ showing that an amount of of R4275.34 for data usage was incurred on the 25th November...on one day! Is that even possible when one is in the country. They were unable to give any information/proof of how this data usage was incurred. On 7 December I received SMS notification that my dispute SR Ref S3-9MZ74-4358 was in queue for processing/investigation and that I would be contacted. Well today is the 23rd December and I have still HEARD NOTHING! I contacted the call centre today and was advised that Candace Petersen was dealing with the matter and a message was sent to her to contact me with an update. Can someone please come back to me to resolve this matter"
