Persistant FGro consultants

I dont know why cancelling something has become such a issue these days, I was going to take out a policy with Discovery through FGro but when it came to me changing my mind and trying to get it cancelled with different consultants since Feb,way before I was suppose to be debited (end of March) none of the consultants wanted to cancel the policy. Came to the end of the month (March) and the policy was deducted from my account after speaking numerous times to consultants and asking them to cancel the policy, now I have to wait for my refund which I never approved to be deducted.
