Poor Service delivery

My Contract had expired with ADT November 2022. In June 2023 - I decided to take a new rented contract. In November 2022 I was charged radio license fee for 2022/23 for a full year. On taking the new contract they mentioned that I will have two months free with the first debit in 08/2023 - however they had charged me on the 01/07/2023. I had complained about this via the telephone to both the sales person and to a person at ADT Via their call centre. I even contacted the sales person via Whats App and also via text message just to give her full details of my issues. Also the installer had taken my remotes from our old alarm system and had promised to have them replaced with new ones to accommodate the new system they installed. This kind of service is not acceptable.
