Non-existent client service

We went online on the 18 May 2022, to book a cruise, discovered the system was charging a hidden charge without explaining what it is for. We phoned and spoke to Zandile and explained the situation to her, we even sent screenshots through to her to show her what the problem was. When she attempted to make the booking, she gets a different amount altogether. So now we have three different amounts, one where you add up what shows what is being charged for, one where the online site adds a hidden fee and the fee from the call centre. Zandile indicated she is going to send it through for investigation and I will have an answer within 24 hours as to what's going on. Today is the 25 May 2022, I spoke to a male person by the name of Evidence who then went to query said Zandile who now only informs him she is going to follow up. So, this clearly means they don't have client service or they don't care for clients that report issues, it's a question of if you have a problem, they ignore it and hope it goes away. And when I ask to speak to a manager, I get informed they are too busy. So, I take it they don't want to deal with client issues.
