Abused

I feel like Tracker is abusing me. My monthly debit order is supposed to run on the 22nd. Today is the 24th and still debit order didn't run. I call in with my small airtime, Lebohang tells me the bank stopped the debit order. I ask her to send me proof so that i can take it up with bank. Then my airtime finishes without getting help. How is the bank suddenly stopping the debit order? Just last week I've been speaking to you guys regarding debit order. Yet again we are here and it isn't the first time experiencing this delay. How do we fix this payment issue? I have just suffered collection fee last week. I can't really be going through this all the time. Money is there but debit is not running?!!!
