Fedhealth ********** Medical aid claims

I am very displeased with their claims department. I have been paying for medical consultations that I am not aware of. I currently reside in Johannesburg but there has been claims paid out for medical practitioners in Bloemfontein. I have contacted their customer service center and the consultant gave me the contact numbers of the practitioner and said I must investigate the matter myself. The cellphone number that was given belongs to a guy who said he was a prison warder and the telephone number does not work at all. i then proceeded to log a query ( twice) on their website after a large sum was paid to a bio kinetics practitioner. I have never consulted for such. I am extremely frustrated because I do not even know how to proceed to sort this out when i have to carry out ***** investigations by myself. My details are now in the hands of ********* and my medical aid savings are getting depleted every single day. Fedhealth does not seem to care about their clients.
