I am not happy of Damelin service

On the 19/01/19 I wanted to register with damelin correspondent and I went through their online registration and it system requires payment before processing with registration and had to insert my Visa card details in order to make payment of R1100 which was required . After the payment went through, system kicked me out. Around the 28 of January I received an email from Karen (damelin Administrator) informing me that the payment has been received and i will receive a call from the person who will assist me with registration but i have been tossed to and fro. Today the 11 April 2019 I'm still not assisted and now I'm being told that they cant trace my payment and I even forwarded proof of payment and my bank confirmed that the money was banked on the 21/01/2019 by damelin. I am not happy, they fail to register me and they are also ripping me off of my R1100.
