I received a notice from Fedhealth that I need to inform them if I will be out of the country over the festive season. I have sent this information on the 2/12 and 4/12 and again in a live chat on 8/12. i even mailed the chat conversation to myself but i have still not had any confirmation with regards to this. I asked to be sent the terms and conditions of my policy but all i got was links and when i told the live chat agent that they simply said it was too large to email! I told the agent that i cant call them and she said that's my only option. I find this is not TCF as I receive mail from Fedhealth on a regular basis and I pay an administration fee so that i can be helped! I want to know if the terms of the policy are such that if i work in Malawi for 4 months if i will still have cover and where can i see this information but i can't seem to get a response.
