Urgent assistance due to poor service given by Fedhealth Medical Aid.

I am a member of Fedhealth Medical. I have recently had a 20% pay cut at work and also divorcing my spouse due to a bad marriage. I am the only provider for my two children a prescholar and high school student whereby I get no assistance from my spouse.Things have been bad since last year. I have communicated all this to Fedhealth that financially I am struggling and ask assistance to move to a cheaper plan which they did allow me. The problem is with payment arrangements with the outstanding amount whereby they only give 3 months to pay which makes my monthly premium still very high and to top it they sent me an email that areas increased now from R4800 to R7000 and seems it will get higher. I need assistance to get a better and affordable payment plan on the arrears and I want to be able to pay my new plan and something on the arrears amount until I am up to date and need to retain my medical for the sake of my kids and also I use chronic medication. I have asked in several emails and telephone calls but it does not get better. There is also poor communication from consultants side. I made an arrangement but it did not work due to my financial struggle and did communicate this. I am disappointed that Fedhealth cannot accommodate me and also assist me. Is this how people are treated when you in need and seek help. I do pay and paid well but things happened. I need help if they can work out a 6 month or 12month payment plan on arrears and let me pay my new plan and the rest in instalments and also stop debiting my account with these high amounts after I asked assistance. Please help me urgently.
