Ongoing Billing Despite Cancellation Request and no response for radio pick

I'm writing to express my deep disappointment and frustration regarding the handling of my cancellation request for the services provided by ADT.

In October, I took the step to formally cancel my services and followed the advised protocol by sending a cancellation email. Upon contacting your team, an agent informed me that a 30-day notice period app****, and as such, I would be responsible for payments for October and November. I was requested to contact ADT to arrange to pick up the radio after the final debit in November.

On November 28th, I reached out as instructed and spoke to the agent. During our conversation, I explicitly requested confirmation of my contract cancellation and the arrangement for the retrieval of the radio and the return of my gate key. I have received and email confirmation that my services was cancelled but there has been no follow-up or action taken since then.

Not only has the cancellation process not been finalised, but I've now received an invoice for services in December. This lack of response and the recurring bills are in direct contradiction to the terms discussed during the cancellation procedure.

After being a loyal customer for 8 years, it's disheartening to experience such a disappointing level of service. This ongoing inconvenience and the lack of closure to this matter are deeply concerning and unacceptable.

I kindly request immediate attention to this issue. Please confirm the cancellation of my contract and provide a definitive date for the retrieval of your equipment and the return of my gate key. Additionally, I urge you to rectify the recent billing error for December promptly
