Still nothing happens

On 7 Feb 2022 I complained on Hello Peter about Yellow Pages billing me for something I did not agreed on. The next day they contacted me saying how sorry they were and that one of their agents would contact me soon. After a few days I got an e mail from someone, saying that they will come back to me. Nothing happened. In the mean while I received two anonymous calls from a device, telling me that they gave me over to their lawyers, Brooks and Luyt for not paying my two accounts that were outstanding. I see this as an easy way to collect money that does not belong to them. In no stage they said from which company they were, or who was speaking.
