ABSA bank has the worst customer service

after being loyal to the bank for years, I started with a mega U account when i was still in my teens and gradually upgraded my account only for the bank to treat me like trash. last month they didn't even bother to debit my car installment and then they decided to start sending chase letters and calls claiming they did not find anything in my account, I went to the bank twice to have this sorted and for them to account for their mistakes, in both instances i was told i will be contacted, well it's a new month and they most probably will debit or not this month, but the bank never even bothered to contact me even after multiple time of trying to get this sorted on my end. anyway, why stick around if you can find other places that can treat you better.
