Formal Complaint of repeated and unsolicated calla

Dear Unlimited Group Customer Service, I am writing to formally lodge a complaint regarding the repeated and unsolicited calls I have been receiving from your agents about motor warranty plans. I do not own a vehicle, nor have I ever requested information about motor warranty or insurance. Despite this, your agents continue to call me more than once a day, which has become extremely frustrating and disruptive. I have repeatedly asked your agents to stop contacting me and even requested to speak with a manager, but no manager has returned my call. This lack of response is unacceptable and only adds to my frustration. I demand that my contact details be removed from your calling lists immediately. I expect confirmation that I will no longer be contacted by your agents regarding motor warranty or any other product. Failure to respect my request will leave me with no choice but to escalate this matter to the relevant consumer protection authorities. Sincerely, Ashley
