Horrible systems and customer service

I were with Discovery medical a few years back and I recently joined them again through my company. I have been trying, without success, to log into the Discovery app and website.. I keep on getting an error message 'ID number and cellphone number dont match'. I phoned Discovery and the answer I get from their IT guy is that I have different details on the banking side of their site and that I have to talk to the banking people to verify and change my details. This is unacceptable and ridiculous. I have absolutely nothing to do with Discovery bank and Discovery are wasting my time and money on phone calls, passing me from one person to the next with no solution. I have never had any type of bank account with discovery. Dont expect help from these people. You have to struggle through a list of automated selections to eventually get to a live person and then that person tells you long stories and want to pass you to the next person. Useless centralised system.
