Frustated Fedhealth client

I have been trying to get a refund on my medical aid which was cancelled because I lost employment. My then boss did not pay our salaries until we decided to leave. I then enquired about the refund which has an amount that changes every time I call, I then decided to claim whatever amount I got last, which is 2500. I started the process on the 13th of December 2021 and submitted everything as required on the 20th of December. Since the submission they have been giving me a runaround and bear in mind I have to make those long calls with money I don't have. All the agents always have a different reason for non payment. Firstly the Finance Department was on leave until the 3rd of January and I waited. And January I call and they tell me I must wait for five working days, and told me before they send the money they will notify me. And then on the 11th of January I call again and they say my claim was not processed the agent **** to me. I call again and they say they have escalated my complaint to the team leader. In all these call I sometimes run out of airtime and they promise to call me back but they never do. I am sobbing because of frustration I don't know what to do anymore. And I didn't cancel my medical aid out of free, I was because I couldn't afford it.
