I smell a rat

First of all my money already went through on my card but I got an email saying finalise your payment. Although it should online it was confirmed. After a long WhatsApp discussion it got confirmed but with wrong date and still not appearing on my app. Another long discussion and they said it's a technical issue.

I then wanted to change the but can not be done on WhatsApp, I have do it when a agent calls me. I confirmed the new dates but it still showed the old dates but told after several calls that is how it works. They also insisted I pay while holding online, which the bank clearly warns against. So I said I will pay and they can call back. The link expired after an hour that it was send. I called for a new link that still didn't come. After three days the ticket that I paid for still doesn't show up on my app. It's difficult communicating and took a lot of calls and airtime and days to solve and still not resolved. Seek a different travel agent, please.
