Beyond upsetting services

I think it is beyond disgusting that I have pleaded with Discovery about the fact that they need to change my payment method to eft, since I'm currently not earning an income and someone else is having to pay my medical aid on my behalf. They out right refuse to change it and are making me suffer even more by the fact that the debit order keeps failing due to no funds I my account, the penalties that I'm being charged are ridiculous and Discovery just couldn't care less, even though they have been getting their contribution every month, just via eft. Never in my life come across such insensitivity or unprofessional client service.
