Inconvenience for customers due to employees capturing incorrect information. Disgusting service!

Contacted your call centre due to Vodacom debiting my account on the 26th when I CLEARLY signed for the LAST DAY OF THE MONTH only to be told that I need to now go to the store (somerset west mall) and to get them to change it and refund me as Vodacom is not responsible for that. How can the onus be on the PAYING client when YOUR EMPLOYEES have captured the incorrect information which has now created additional bank charges. Expect and invoice for petrol and bank charges. I should never have changed over from CellC. Vodacom your service disgusts me! I will NEVER recommend your group to anyone. Not even my dogs.
