HN stays on Airbnb are *****s

On the 2 June 2022 I was due to travel to Sandton, I booked my accommodation with Airbnb and paid them R2100. Then I received a message from the host and they requested a R3600 security deposit. I was so angry as this was not reflected on the payment which I made to airbnb. I then sent airbnb a message asking them why must I pay this security deposit and they indicated to me that the host has a right to charge the deposit. Not knowing that this was not allowed outside of the airbnb portal. I then paid the deposit into their Capitec account as they were listed as a Superhost. 1 day before I traveled they canceled my booking saying I did not verify my guest and they are forfeiting my deposit. They then went on to block me on the airbnb messaging app from sending them messages. These were several red flags that I was not aware of. I was ****med for R3600. I Googled the address and what comes up is not what is reflected on their page. They also have **** reviews. Airbnb have not helped in any way. The airbnb ambassadors do not read properly and respond accordingly. I requested them to investigate this host but all they do is just close the conversation. I have made several queries and I also told them that I will not take this lying down. I will use all avenues to make people aware of the **** on airbnb for hn hotel stays.
