Lack of support services

I joined Discovery in Jan 2016 and my membership was terminated in May 2018. I rejoined in June with a clawback of R14460 and i was given a new membership. End of August that membership was terminated and i am trying to re join the discovery medical aid and i have been advised that i owe R8200. I requested for them to offset that 8200 onto my new membership but my broker and i were transferred to three different departments and nobody could assist us in getting this clawback offset. staff are not trained or held accountable to know what is going on with my account i have been employed for three months and i do not have medical aid due to no support services from discovery.
