Capfin Bad service for new loan

I have been with Capfin now for almost 1 Year. Never had problems with them. Everything went smooth. This month all of a sudden I'm batteling to get a topup loan from them. I app**** on the 14th December and send them all the requested document like I always did in the past. Then I started getting email and Sms's that they cannot read the documents. I then resend it. Then another email and SMS saying they need an October statement which I have send. And this in now been going on for more than a week. Sending me an email the bankstatements frequency is not right and now I received email saying now my bankstatemnts has expired. I have spend over a R100 to email the documents to Capfin now. I have explained how many times over the phone that I get paid weekley. They have al statemnts from Oct to 14 Dec that was was my last pay date for the year. I have even circle my paydates on bankstatements. Copy of ID was also send as requested. I get emails back fro Charmaine September saying the problem will be solved that was 2018-12-21 . Bus no it was not sorted out. This morning the circle started again asking for Oct bankstatement. If I call the call centre they confirm documents are there they can see it but they keep on asking me to send same documents over and over. I;m very very frustrated. Please can you sort this problem out
