Wrong number money transfer

Good day My mom mistakenly sent money into some strangers Capitec account holder. After discovering that she made a mistake she then called Capitec and also the person who had received the money. The agreement was that the recipient should take 10% of the money and send the rest of the money back to my mom. Few hours later the recipient blocked my mom's calls and Capitec can't help us get the money back.

Capitec advised on opening a case, unfortunately we couldn't get help from the Police Station as well. I'm very disappointed with Capitec service.
