Nedbank's threat sms

I received an sms from Nedbank with reference number - DEB39009. According to Nedbank this is a final warning,No payment received. They are proceeding with warrant on my goods<br> <br> I don't know what they are talking about because I only have a personal loan account with them and it is up to date<br> <br> I want Nedbank to either stop sending me this kind of sms or give me details of an account that is not up to date
