FNB fails transgender customers

My bank cards had expired. I contacted the number SMSd to me to arrange delivery, I painstakingly explained that I did not use my legal details because I was transgender and asked the agent to please use my correct name, The call got cut off. I called back and got another agent. When I asked her to please not call me ma'am, suggesting that she rather call me by my name, Mx Tish White, she put the phone down on me, Now, totally convinced that my transition is a joke to FNB, I called the number again, horribly referred to as my deadname and incorrect gender, It was a humiliating and hurtful experience. Clearly your staff don't know how to approach a transgender client in their line of work. As we make up 4% of the population, maybe it's time for that to change. As attractive as the new cards are, they again have my dead details on them, which makes me want to rip them up an get rid of them. They are just another reminder of a world that treats us as a joke. I have been legally trying and failing to change my details legally for 4 years. My workplace sees me as Mx Tish Lumos White. My friends and family do so. Why is it so hard for a bank to get this right? I've had this account for 11 years, every time Ive raised this, I have been dismissed.
