Terrible customer service and credit controller service

I am disgusted at bonitas credit control team and their customer service department. I keep hold to speak to customer service and they answer and immediately drop calls. Imagine how many other customers have to experiance this. It is a waste of my time waiting through all those promps to get through to a consultant if you happen to get through to a lazy one. They are hardly helpful at all when having to resolve my queries. I even spoke to a customer service supervisor who was suppose to assist me with a recon of my contribution account and the advance/arrears paying client issue inhad been set up wrongly and he has not gotten back to me. Now credit control is wanting to debit a large sum from my account this month with no permission from me. I have sent Nake an email over a week ago to advise that they are not authorised to debit this amount and only my monthly contribution, but to date he nor anybody has gotten back to me. Bonitas offer a great service but the people working in their organisation are making clients very despondent about wanting to utilize their services. I am a very unhappy client because of the incompetence of the people who fail to deliver a great service for this really good company.
