What a horrific company

We have two contracts with cell c. And one we were told that if we pay up a the balance we could upgrade which we did the past Monday. We called retentions department and they said we could go to any store to do the upgrade. So we decided to go to cell c in centurion mall and all the problems started. A trainee helped us and didnt bother to listen to us as they needed to call the upgrades department to do the upgrade. She didn't know what she was doing and then said they couldn't do.the upgrade. She called Edwin who came to help but he was so rude and didn't care and spoke in afrikaans to the trainee because he thought us being Indians would not understand him. He told her we have to deal with what they say. Eventually there wasn't nothing they were willing to do. They just kept mumbling and when we walked out it was all a big joke.
