Disappointed

I'm very disappointed and feel mislead. I was late for my flight from joburg lanseria to Durban. I called in at the call centre an hour prior to my departure to try make arrangements and changes for the next flight. The lady I spoke to requested for my credit card details. I explained that I had no credit card but a debit card that I made my booking with. She said she could not assist. I asked if I should go to or tambo and she suggested that I go to lanseria where I had made initial booking. The lady at lanseria tebogo was helpful and asked to see my card. She confirmed that Candice could have made changes telephonically. I wasted my time going to lanseria since they couldn't do anything with initial booking. I had to pay double for a new ticket and irritated that I had to wait for a 18.25 flight when there were 3flights at or tambo prior to the 18.25.
