Unable to let a debit order to go through

One of my debit order bounced because there was R100 short of the full amount, every other month, the account runs in the negative, but for some reason this month is different, can someone please contact me to cancel all of my accounts immediately, have been told by the contact centre agent to contact premier service as they will be able to help, I tried calling but held on the line for over 5mins, thats not premier service, please someone contact me urgently
