Poor service

I have an account with Payflex and they were deducting every 2 weeks,the last payment did not go through,I queried it and they told that they need authorization to deduct the money, I asked them how they deducted the previous amounts,I tried making a payment manually,it did not go through, they take time to assist and assist adequately at that,now my account is handed over,I asked them why as I have been communicating with Payflex(Nomsa Sithole),she did not resolve my issue even after I sent screenshot to her.
