Pathetic service

We joined discovery medical aid effective 1 February on the call l was advised that there was no waiting period since we have been on continuous medical cover for over 10+ years.We received our medical certificate which showed 3months waiting period . We queried this and was advised that we were misinformed by the agent to which l argued that the call was a binding contract as terms and conditions were read. We were then advised after an agent listened to the contract call that the waiting period was waived.however on the 2nd of February we tried to get medication at the pharmacy but was told we were on waiting period . I called discovery on Monday and was told by a client specialist that l will get feedback by end of business.its over 24hrs now and l haven't gotten feedback. THIS PATHETIC DISCOVERY YOUR CONTACT CALL ARE BINDING SO WHY HOLD ME AT RANSOM
