I am highly furious with Vodacom Customer Care and their lack of service - Cellphone number ***

Good day. I have been trying for a few months to have Vodacom remove a bundle on my account. They told me that they were going to get their technicians to call me and have the issue resolved. I refused not to pay my account after I told them many times to remove the bundle. They told me it's done then the next consultant calls and it's still on the account. Nevertheless, on the 19/05/2021 a Vodacom consultant called me again and this time I was furious because no one ever got back to me regarding my query. She advised I pay the account because it's going to give me a bad credit record. I told her to first sort out the issue or get a manager to contact me. I told her everything about my conversations I had with the previous consultants. THIS GIRL SLAMMED THE PHONE DOWN IN MY EAR. Is this the attitude that "Customer service consultants has now" Do they even have the right to do this to a customer. She called from ***. Bad thing is I never got her name.
