Bad customer service

Capfin is the most harrasing company. Firstly they approved me to have power of attorney on my husbands account and a arrangement was made. Now that we want to do payments at pep or Ackermann they refuse to speak to me, say there is no proof of power of attorney but I have the proof it is received . Theu keep on phoning 24 hours a day. We get around 10 calls and when you speak to the call centre the they just keep on talking like a robot. We cannot discuss anything with them. Their client care relationship is up to ...... and they don't come to any agreement or try to resolve the issue. They are the worst credit company to deal with.
