Ocean Finance / Loan scammers

Good Day.

Early February I had received an sms regarding taking an affordable loan of R50 000 of which few days later I decided to contact Ocean Finance regarding the matter. I contacted the office on [protected] and [protected] and [protected] to get full details on what's needed.
A lady by the name Portia answered the phne and I asked her that I had received an sms regarding a loan what's the procedure.
She then told me to send my pay slip and copy of id.
I was then asked to pay R2000 of which they call as an insurance"""".
After I had paid that amount I was then told by Richard and John to pay another amount of R2850", that's when I asked why am Ipaying for this amount and they said this is a cost of transfer amount, after paying for this amount I sent them the proof of payment but still did not receive the loan as they promised and please NOTE: they sent a letter saying definately th money will be in my account.
When I contacted the office they said I need to pay R2300 for Maintanaince and R1980 for Monthly service fee of which they claimed thay its refundable.
After paying for these 2 amounts STILL no payment was done, then again they told me to pay R5600 of which I refused to pay, then they told me I'm holding the process up and started shouting at me.
To my suprise if you ask them their address they never disloce their information but instead theyll ask you for your id number.
Please assist with this matter because a lot of people in JHB have lost their money due to this scam.
Please note that these people are based in Braamfontein in JHB - [protected].
