*********** and not well trained call centre agents

The call centre operators at the Vodacom Call Centre is *********** and not well trained! I cancelled my data contract 2 months ago and realized they were still deducting money. Called yesterday querying the deductions and spoke to a lady called Pearl. She then told me there was notes on my account requesting for cancellation, but this was never action. She then advised me that she will action this and i should get a refund in the next 24hours and provided me with a reference number. 24hours has come and gone, so i called again this morning wanting progress on the request. I then spoke to a guy Oupa and gave him the reference number. To my surprise i discovered that the reference number i got from Pearl was a reference number for cancelling the contract effective 30 June 2019, and she never put any notes on my case. Where does this leave me now? Please can i have my refund today without any further delays! Your service is terrible and i will never recommend it to anyone! I'm done! I want my refund today!
