Medical Aid Cancellation

Poor experience and poor service. I know companies have a 1 month notice period for cancellations, but sometimes there are circumstances that don't allow for that. I previously had no problem with Fedhealth and have hardly had to make use of my medical aid and normally would not be leaving them, but with my current company closing down my section, I had to make a move over to another company quickly, which I have. This new company has it's own medical aid and they require us to be apart of it's scheme, of which I have informed Fedhealth, but I get back the same standard response that you need to give 1 months notice. This is a problem for me and I need this resolved asap, they then tell me the cancellation department will be in contact with me within 3 days! Just alround lack luster service and assistance when I really need it.
