Poor service as usual

I posted a complaint more than a month ago and standard bank rep**** saying they will treat my matter with urgency yet no one bothered to phone me. They just dont care about an individual and if they lose a client it really doesn't matter. Standard bank is the worst bank when it comes to service. I had called in over 10 times to initiate a payment holiday on my loan and the last person I spome to said that it is sorted and they will not debit me yet as soon as money went into my account, standard bank debited me immediately. I just dont know what to do except change banks.
