Bad airline

Airline doesn’t respond to any of my queries. Firstly, my lock was broken off my bag. I opened a case at the airport but no case number was sent to me as promised by the lady at the Desk at CPT International airport. My second bag’s wheel was also broken off and also nothing was done about the damage. My main query is regarding a refund on seats which I accidentally booked and paid for, before the 24hour booking period opened. I called in the moment I saw the website required another payment and the agent promised me the refund will be done in 48hours. It’s been more than a week and nothing was refunded. I sent in so many emails regarding this but no response. I reached out the social media platforms for assistance but unfortunately they couldn’t be of any assistance either. I will never use this airline again. They are very unprofessional. The air hostess didn’t even bother informing me about what to do in case of an emergency with my baby. It was my first time flying with a baby which I told him and he walked multiple times pass me without saying a word even though I told him, it’s my first time.
