NO customer service, zero, nada, null

Sent emails with no response, no reference nr's, just zero feedback. Trying to get a refund, sent a mail on 30 APRIL and 24 April...zero reply. Requested the refund as per the steps online, after I requested that the debit order is stopped. System shows another debit order will go off....how does one get assistance? Why have a "customer care email" when no one responds, waiting on calls for 20min just to be told "you are at the wrong department" Will never go for vehicle finance with Wesbank again
