Membership cancelled without notification!

I received correspondence of Bankmed's intention to cancel my membership as a dependent unless I provide motivation of why I should remain as a dependent on the scheme. I submitted my motivation as requested and received a response stating that my request will be sent to the appropriate dept and I will receive feedback within 2 working days. To date I have had no feedback, instead Bankmed has chosen to ignore me completely and cancel my membership even though they made sure to deduct my premium! I have been with Bankmed for 11 years and I have a PMB and chronic condition, i found out my membership was cancelled whilst trying to claim for my chronic meds this weekend. When I phoned the call centre on Saturday the response was that the admin dept is not available on weekends and there are no managers available to assist. So i have been left without meds and i am going to run out tomorrow! Due to a kidney transplant i cannot be without meds for even one day but Bankmed is now in the business of playing with members lives! I was promised a call by 8am this morning and i am still waiting! Absolutely pathetic!
