usless service

Once again disappointed I have a loan with Capitec,been paying through the app last 3 years,now for 4 months the app isn't allowing me to pay it,so having to go unto the bank,date is set to pay 25th,i received my pay the 25th around afternoon time,now wanting to pay it omcr again couldnt,so which put my account in arrears due to not being able to pay it on the app,which no one can assit and give me an answer as to why,now through this my clearscore have lessened which is very very unfair,due to *********** people that cannot assit with the issue.
