Harassment after debit order goes off

At 7:00 I received a call from Nedbank call center, when I asked what it's concerning, I was advised it was a courtesy call, I became very upset as my husband had advised me the entire day, the same call was coming through, my debit order went off early parts of the morning, to me this is harassment. I was advised by the consultant thereafter to go to the ombudsman and ncr, cause out of frustration I advised him I was going to note this on hello Peter. The arrogant consultant was very rude, he advised he will not disclose anything further as he did not confirm my ID number and the calls are recorded. That's very good to record calls, what is the purpose to run a debit order and still get unnecessary calls. There is no need to contact me on numerous occasions when I have a debit order in place. Every month I have the same problem, harassment of sms and calls. This is uncalled for. Poor pathetic service. Rate Nedbank at this very moment a zero for poor services.
