********* and Unprofessional?

I am complaining about this group because of their association with the Nimble Group, whom I am experiencing as harassing me for a supposed debt that I have already paid. This debt was supposedly incurred over a year ago, with no details being communicated to me by Nimble or Norman Bisset, despite my complaining about both on Hellopeter. I have checked with Vodacom, who assure me that I have paid this debt. I would appeal to Norman Bisset to stop their debt collector Nimble from harassing me. If not they are guilty of alleged ********* and unprofessional conduct.
