********* & unacceptable use of power

I do not know these people from REVCO who keep on sending me threatening SMS'es mentioning that they are handing over my TV licence account. I sent several proofs of payment to them, only to be continuously hit by the same threatening messages. They have a nonfunctional WhatsApp number *** which when you respond to it, no one replies back or even call. If you call the number it rings 2 or 3 times and cuts. These SMS'es are extremely annoying, these people must STOP this nonsense.
