Is this *****

On the 20th January 2020, I visited Vodacom Galleria to downgrade my contract, Charlene falsely sold me a contract. She invoiced me for a higher amount and when I pointed it out to her she told me that it was an error that would rectify it before its processed. She also told me that I would receive 20gig data by that evening. When I checked my data the next day, there was no change. Two days later I called the customer service and enquired about my deal and they advised me that I will be paying the higher amount and my data will only reflect at monthend. I immediately called the store and spoke Charlene and she insisted that there was an error and I was going to be paying the lower amount. We agreed that I would be canceling the contract as the phone was still sealed as I sensed that something didn't add up. I drove to the store 100km and returned the phone. She advised that she will refund the admin fee into my account the next day. A week later I called her and enquired about the refund, she said that she will call me back. Last week I called her manager Anneline and explained her the story, she promised to call me back. Since I did not hear from Anneline, 6 calls her back today. Firstly I left a message message for her to return my call, but she did not so I called her instead. She remembered me calling her last week but tells me that she was out for 2hours.... I reminded her that I called her a week ago. She couldn't tell me anything about my refund and took my details for her operations manager Angela Naidoo to call me, and I am still waiting. This is ***** and I would like to warn the public out there. I have made several calls and seems like vodacom galleria has a tendency not to return calls, can someone look into this.
