Policy not Possible

I spent an extremely long time on the phone to sign me and my family up for one of the plans at Oneplan, then they just never debited my account. When I inquired what the matter was, they said that the debit order was refused. We checked the banking details and the account they had listed as mine is not mine, and I have never heard of such an account in my life and I asked them to rectify their mistake. Subsequintly they notified me per text that the policy has now been cancelled due to non payment. I would be very carefull dealing with a company that debits wrong accounts and is unable to rectify it. Luckily I did not cancell my medical aid yet, because that was the plan.
