Misleading Call Center Agents

I used hippo services to optain a cover from Medschield under Medscheme Medphila option which the guy said it would be immediate cover for GP and accidentally incidents. However when trying to use the cover it's not active from the 1st Feb 2023 instead will only be active from 1st May 2023. This is unexceptable and breach of contract as all calls are recorded. The only reason I agreed to it was for the effect date. I will not pay for a medical aid that I can't you for 3 months. That's why I am asking again and again to have my money refunded and the medical aid canceled as it not even active as yet. So please honor my request or I will have to take this up further to ombudsman.
