Mr. Justice A.P. Chowdhri, President— Brief facts of the case leading to this appeal are that the telephone in question was installed at the residence of Smt. Preet Dhankar, hereinafter referred to as the complainant, in January, 1986. Since the date of installation till the disputed bill dated 1.7.1991, the bill hardly ever exceeded the number of free calls allowed by the department. Suddenly on 1.7.1991, the complainant was served with a bill for Rs. 20,056.50 for the period 16.4.1991 to 15.6.1991. The bill included 16 ISD calls made to USA, UK, Switzerland between 0025 hours to 0623 hours on a single day namely 19.5.1991. The complainant immediately brought the aforesaid facts to the notice of the department and she was allowed to pay a split bill of Rs. 358/-. The balance amount was not claimed for a long period. Ultimately, after nearly three years notice dated 25.7.1994 was served on the complainant requiring her to deposit the balance amount of Rs. 19,699/-. The opposite party regretted any effective action on the basis of the complaint made earlier by the complainant. The complainant having failed to pay the balance amount, the telephone was disconnected in August, 199
