Bad /worseCustomer care by standardbank

Last year I experienced challenges resulting in loss of income .i requested standardbank to deduct my policies from savings but they still continue to deduct on my dormant account.This are old policies and standardbank never wrote an email to me regarding this policies or update .they only deduct money .i want this policies to be resuscitated and deduct from my savings account.i have notified the bank about this normally but to date they are still deducting there .i tried calling onother number they say they have high call volume ,what’s that?.I ve been with standardbank from 1992 when I was still a student .I m a loyal customer for this bank but I cannot afford to loose my policies due to poor communication .The policies are MDR***,MDR***,MDRMR*** ,The monthly instalments are small it’s not difficult to pay
