Air Asia — Did not allowed to board flight. B2NCQZ

I was not allowed to board flight dur to no covid test result. I told them to cancel the flight at the counter they said they will only refund noshow tax amount which is fraud. They didnot allowed me to board flight and even they are not refunding full amount. I had my covid test immediately and the result is negetive. This is fraud and they are looting my hard earn money. Even in ticket they didnot mentioned that covid certificate is necessary. This is purely fraud from airasia side. Kindly take action against them.
