AIRBNB NOT REFUNDING ME

I made a booking early in June for the 5th to the 7th of July. I made a payment to reserve the place and then the remaining balance was deducted from my bank. On the day I had to check in at 3pm I text my host and he tells me that he's not getting ahold of the cleaner to clean the place. I tell the host we can check in later and he insisted on me having to cancel the booking and ofdred to refund me immediately. I canced as per his advice as he even advised that we cannot check in even later we needed to cancel and so we did. I received 2 emails shortly confirming that a 450 and 500 refund had been issued yet I didn't get the money on my back account and this was on the 5th of July the day and time I had to be checking in. Imagine all this dissapoint after the host was quiet whole day and only told me this info when I was asking him about the self check-in. Wednesday the 8th of July only R500 was paid from Airbnb and not the R450 I immediately advised the host and he said as it was 2 separate payment I needed to allow 1 more day and until now I have never received my R450. The host advised me to refer to Airbnb as the money was coming firm them, he said and I did that and I have never received an acknowledgement of query whatsoever. I'm stressed because I need the money. Please help. My email is ***
