This bank is abusive

I am tired of being punished for being a customer. From endless unexplained charges that add up to hundreds of rands a month, to unresponsive and dismissive customer service, every direct interaction I have with this bank feels like harassment. I've been trying to get an issue resolved since Thursday and they keep giving me the runaround. They won't even do me the courtesy of acknowledging fault and calling me. I have to keep calling them to get a mess THEY caused to be resolved. I do not recommend anyone use this bank and as soon as I can I'm moving to a different one. Speaking from experience, banking with FNB makes me feel like I'm in a relationship with an abusive partner who knows they can harass or punish me, and get away with it.
