Failure to reimburse money owed to me for an extra payment for a weekend away in Bela Bela

One would never expect that people would not reimburse a customer for an additional R1100 that she requested that I pay to confirm the accommodation I had booked for a weekend when the full amount had already been paid to Afristay, the website through which this was booked. She does not answer calls, she doesn’t answer WhatsApp’s and to date, she has provided one excuse after another, including the fact that the payment was made into my account on Monday, 29th and that it takes 3 days to reflect in my account. It’s now 5 days later and still nothing. This is not only theft but highly unethical and unprofessional. I was hoping that it would be resolved but unfortunately, I have had to go to the Police Station and lay a charge. I would suggest extreme caution when dealing with this person. Sadly, I have received zero support from Afristay in resolving this although the booking was done through them. I fail to understand the setup where people pay a deposit to Afristay and the remainder goes into a strangers account who in this case was someone that was not to be trusted.
