Fed up!!!

It was a struggle from the beginning to rejoin the medical aid, after being in the USA for 1 year. We had been members for almost 9 years! Eventually after back and forth emailing and a letter from the Urologist, we were covered. After an email to resign, I received my member certificate showing the last active date 30 March. I specifically said please ensure that we are active until 30 April. We will be leaving for Canada on 7 April. I don't want to take any risks when it comes to medical coverage. Why is this so difficult to understand and sort out! I'm fed up with all the referrence numbers and no resolution!!
