Third party billing

There is a company called Nudebt that is debiting my account for some monies I don't know since I don't have outstanding debits with Telkom and apparently Telkom instructed this company to debit my account. Now understand the type of a client you are dealing. The POPI Act stipulates that when a company gives a third party details of a person they must be used for the purposes they were acquired for in the first place. Now Nudebt trying to ***** money from my account is an infringement of my right and of the POPI Act. Telkom beware this is war and you will pay me back every cent I have incurred as a result of your foolishness and negligence.
