Easier to cancel and re-apply than Changing details

I joined Discovery Medical aid in August. The hole proses, application and debit order details (3rd party) was given telephonicly.

The 3rd party has since changed his bank details.

I phoned in to change the debit order details but was informed it could only be changed online or to download a form, complete, scan and send.

I have since changed it online but was informed I need a proof of account holder and details letter.

I was givin no way of sending said letter, I submitted it trough live chat online.

I was informed they require the form from me as well.

How was I able to give my initial details telephonicly but to change my details is more than a two week hassle which is still not completed! I'm truly thinking of canceling and then just re-applying telephonicly. What are people supposed to do that are not fortunate enough to have access to a printer / scanner.

I'm a mom of a 10 month old colic baby. I do not have hours to spend on the phone holding for the correct department only to be given the run around.
