Money man *****ulent

Good day I'd like to lay a complain against Money Man. I had a loan of R4000 with them and they were deducting 1600 plus 345 the they described as an insurance incase I lose my job. I was supposed to finish paying my loan in August 2024 but they did not deduct the R1600 but deducted R345. They continued deducting these R345.00 and in December they debited twice. I requested for a refund of that other R345 and they said they were going to sort it out in January 2025. In Junuary I sent them an email and they told me I'm still owing them R1600 and they have handed over the account to their legal team. I have been communicating Andrew Mattheys their manager and when asking him what was the reason for deducting these R345 for four months he is not giving me an answer.
