    在"鑒于"之後加上"各電訊服務提供者的營運和銷售存在不少漏洞， "在"不斷增加， "之後加上"而市民的投訴又往往得不到政府部門的有效跟進處理， "在"收費電視， "之後加上"訂定相應的罰則， "及在"標準合約條款"之後加上"此外，由於香港房屋委員會與收費電視營辦商簽訂協議，該等營辦商可進入大廈鋪設及維修公共天線系統，並調派前線銷售人員，以獨家提供維修及供應服務作為招徠，向住戶推銷其他各種商業服務，以不當手法誘使或誤導住戶與他們簽約，對居民造成很大困擾就此，政府必須採取措施打擊上述違規營銷的手法，並主動告知公屋住戶該等營辦商的權責范圍，遇有營辦商作出違規的行為或居民舉報營辦商的違規行為時，須立即追查，並向有關營辦商發出警告及作出處分政府亦須檢討現時消費者與電訊服務供應商所獲系統資訊並不對等的問題，即消費者無從及無權得知他們所選用系統的真實資料，令他們只能按服務供應商單方面提供有關通話量通話系統及通話時段的記錄繳交費用，遇有消費者質疑上述資料時，往往只由服務供應商作最終決定，消費者無從申辯或查證就此，本會促請政府盡快研究如何就各類電訊服務包括收費電視本地及跨境電訊網際網路等的提供，確保消費者享有知情權選擇權覆核權投訴權及索償權" 。
