debit order

Good day. My debit orders for my accounts was stopped reason being I received only half my salary this month. I was contacted by an agent this morning and I advised her to contact me during my lunch break from 12-1pm as I am in a call centre environment and cannot be on my cell phone. I waited for the agents call but nothing. The agent phones at 1:25. I advised her to call on my tea break at 2:30. She calls at 2:25. I told the agent to call at 2:30. No call. I do apologise for stopping the debit order but it was beyond my control. I will try and make additional payments to cover up for the debit orders. I have also changed my banking details and am awaiting the release of the account and confirmation letter. Please advise where can I send my new banking details. Kindly respond via my email address.
