Collection agents calling via a bad telephone line connection ie unclear and totally misinformed

Nedbank Home Loans - WWWWWhhhhhhyyyyy did a collection agent phone me today????? My account is not in arrears!!!! Not acceptable Nedbank - absolutely not on!!!! Secondly - do not correspond with me regarding my bond in any way, shape or form, via the telephone!!! You have something to say or ask, do it via email or an official letter. I want a record of all communications from Nedbank regarding my Bond. Banks - you are all aware you are skating on thin ice and us consumers know our rights. For your information: I did record the call and am very happy to send it to you so that Nedbank can hear for themselves how *********** the collection service staff are that you are utilising.
