FNBs Lazy & unaccountable staff

Appalled by the lack of service and assistance from my current bank FNB. I have been into the bank multiple times over the years and verified my details online and my name, surname and address are still incorrect on my bank statements. My details are correct on the system, etc just on my statements it’s however they decided to spell it. Been on the phone over2 hors and get transferred to over 12 people and no one will help, wrong department, etc cause no-one a am applying for a home loan and they have spelt all my details incorrectly and despite me trying to update them, I get told only my new statement that will generate in the new month will be updated from there, they can’t assist with updating previous statements. It’s their staffs mistake and laziness and they cant / wont help me. Also, they INSIST on us verifying and updating our details but their staff are just too lazy to spell / and anything right anyways and then they take no accountability anyways. Complete joke and cannot wait to move away from your UNHELPFUL and LAZY company.
