Call Centre using contact details without consent

I was contacted by a Call Centre advertising "CompEat" which is administered by Right Click Media. The number came through on my phone as "NuDebt" who are a debt collecting agency. It transpires that the same call centre works for both agencies. They evidently pass contact details from their debt collection department to their sales department without consent. NuDebt have been incorrectly chasing my company for a debt that is not owed. I have had tremendous hassle with NuDebt despite providing documentary evidence proving the situation. NuDebt have taken money from my account without legal right or consent. I asked the sales consultant why I would ever wish to purchase anything from the same Call Centre that is also hassling me for a non-existent debt collection. She agreed to take me off their list. I am considering whether I have any rights under POPI to pursue this matter.
