They don't want to refund our 30 unused credits

It is now difficult for the kandua team to refund us our R300, almost a month trying to reach their support lines. We worked with them for 5 years. **** leads and repetitive leads has been sent to us, we complained to no avail. Now that we do not qualify to work with them, we had 30 unused credits which Kandua should refund us. They are simply refusing to refund by sending back emails for the whole month telling us "they will attend to our refund as soon as possible" If you have never used kandua and you are an artisan looking to join them, then we advise you to stay far away from them.
