Third attempt to resolve ********** activity - ongoing query for a month!

This is my 3rd attempt and complaint on Hello peter at trying to get Vodacom's attention. a Manager by the name of Randell called me last week assuring me that that the ********** activity would be resolved and that my contact would be cancelled as per my request. I asked that a mail be sent with confirmation that this has been done. I have not heard from Randell again , I have received an email 15.02.2021 stating that they have been trying to contact me , when i checked the number stated on the email , the number was incorrect. They went on to stating that the router in question has been used( this is what I have been trying to tell them) it is now almost a month and Vodacom has again failed to resolve this issue.

Hopefully this will attract the attention of their useless , inconsistent staff! Vodacom , you as a company should be embarrassed by the pathetic service you give your clients!

When will my query be resolved?????
