Poor service

I am severely frustrated with the service I have received from Capfin lately. I have been an ongoing customer of theirs since 2017. Paying my loan on-time, never had adebit order returned and been getting top up loans almost every 3 months. For the past 3 months they keep declining my application, even though my loan of R8000 has been almost paid off. They do not give proper explanation as to why it is declined. I am disgusted that they can treat a 2 year long customer like this.
