vehicle finance system outdated and useless customer service

I regret choosing standard Bank for my car loan. They are useless, I have been calling them to sort out my debit order they still haven't. I had to make a direct deposit twice. I have asked to have them to change my debit order date, they charged me for debicheck but my debit order date was never changes. I spoke to the consultant and they keep saying they have escalated my issue and none of them have cc'd me in any of the escalation mails nor called me back. I have no visibility on my VAF account I have to call for any query but clearly I am not getting any help. I am even considering refinancing my car with other banks. I thought as a standard Bank customer it made sense to have my vehicle finance with standard Bank when I was approved by other institutions, little did I know what I was getting myself into. I am sick of being disappointed by this bank
