FAIL!!

I recently upgraded my Fedhealth plan to a new membership which took in effect the 1st of August. I then noticed no debit order going off end off July and was previously informed that they do not have my banking details. Bearing in mind I had cover for July I wanted to find out if I need to make a manual eft cause I was not sure what the implication might be from changing to a new plan. <br> <br> I spoke to Fedhealth, I was informed I owe nothing, I actually confirmed this twice. I then received a statement for my old membership which also showed I owe them nothing. I have used the funds for the contribution for other debt of mine, now 4 days later I receive and SMS telling me I owe them money and no claims will be paid out to me unless I pay. I now need to suffer because of their mistake and the supervisor has the audacity to tell me I knew I had cover I knew I had to pay, after telling her this was exactly why I phoned in and they told me I don't owe anything!? SO HOW WAS I THEN SUPPOSE TO KNOW I HAD TO PAY IF YOU TOLD ME ID DONT!?
