Payment without istallation

I am writing to formally express my deep dissatisfaction regarding the handling of my recent service request. I contacted your company to request a new WiFi installation at my premises. However, instead of processing this as a new service application, your team proceeded to reconnect services under the details of a previous occupant. This error is both concerning and unacceptable. It is extremely troubling that such a mix-up of customer information could occur. Proper verification procedures should prevent the allocation of services under incorrect account details. Furthermore, payment was processed despite no installation having taken place, which raises serious concerns about your internal controls and billing practices. I respectfully request the following: A full investigation into how this error occurred. Immediate correction of my account details. Confirmation of the correct installation date. A refund or adjustment for any charges app**** without service delivery. I trust that this matter will be treated with urgency and professionalism. Please provide written confirmation of the corrective steps being taken within 48 hours. I look forward to your prompt response.
