ONE MONTH LATER AND PMB RELATED CLAIM NOT YET PAID IN FULL

I have called Bonitas with regards to two claims that's were PMB related that were not paid in full. They gave me one reference no for both claims. My 1st call was 11/06/19, then 25/06/19, then 28/06/19, 05/07/19 and again today 11/07/2019. 5 Calls and one month later and only one account was resolved as they now said the other one was only referred on 28/0619. I spoke to 3 people now and not one person can resolve this issue. I just wasted another 32 minutes on the phone with Bonitas. Every time I call each call is over 40 minutes. Each time I ask to speak to a Manager, they transfer me to the wrong person / department. This is totally unacceptable and extremely frustrating, this matter should have been resolved in the time frame after the first call on 11/06/2019. I need a manager to call me back as a matter of urgency.
