Bonitas not resolving call since 05/10/2018

Closing calls but not resolving them. I have a complaint since 05/10/2018 that cannot be resolved. I called in to find out if all my GP visits are done, and the consultant confirmed that I still have visits left for my daughter. Then i receive a bill from my Dr. to say the bill is not settled. I have tried on numerous occasions to get this resolved but Bonitas just refuses to deal with this matter. 1st time I called, they told me they fired the person who told me there is still funds. 2nd time they told me they not paying so I asked or a supervisor to call me... "still waiting..." 3rd time no manager available. 4th time just no response.... should I go... my ref number is 051018Q1HR03
