We are being ****med please help

I had the worst experience with this company called Business Entry Directories. They give advertising a bad name. I need some assistance please. I work a a GP. practice on the 13 August 2024 we got a call from telkom so the agent said (Thembeka) but later found out actually she was calling from a company called Teleacc2024. The conversation was totally misleading by the agent and then for the past 5days we have been receiving emails and calls from Sharan at that company saying my boss has to pay R12 000 for a product (online adverti*****t) which we didnt even proof read or approve. I am a P.A. at this establishment and I can clearly say we are being **********. I asked for the recorded call but this lady is rude and unhelpful. She has been sending threatening emails, to hand my boss over to her legal department. All I know we signed the document to say we changing to fibre on our usual telkom line. We didnt receive any information on our add but being told we signed documents on 13th August so we have to pay for this on online adverti*****t. We didnt want an online adverti*****t. The agent Thembeka deceived us on that call she made and this Sharan lady expects us to pay for something which is totally ******* according to my opinion. This is not professionalism but a **** I believe and I ask everyone out there to please beware of this. Can I please get some help regarding this matter from the Advertising industry.
