Bad service

This medical aid initially promised me so many benefits, but i ended up having to pay most of the time. So i canceled it as i received a better offer from Dischem. When i did i was told i would still be able to use it until April. Which i did. I was then charged for end of April and May. When i queried the May installment i told its the last time they would be deducting. Fast forward 6 months later i receive a statement stating i have a balance of R2900. Which i queried on their emails. There was no response. I thought i will wait for them to call me. It is now a year and a half later, nobody has ever called me from Fedhealth. What i did receive from them was an ITC letter and a number to call. Which i called. I was kept holding for 25 minutes yet the matter was still not resolved. They told me that there were R300 amounts which i had to pay, which accumulated to this amount, for what, nothing was clear. In order to just sort this out i requested to then make an arrangement. I was refused that. I requested to speak to a supervisor, i was again kept on hold until i ran out of airtime. It's been 2 months ago now. Noone has bothered to call me still. They are the worst medical aid i have ever dealt with. No service whatsoever. They are just a ******* and are a bunch of ******.
