I have booked a new mobile vide ID No. SPTP[protected] with your company with exchange. But at the delivery time, delivery boy deliberately challenge my old phone. I assure your company my old phone is original and in best condition. He demands me Rs. 500/- for pasting rear panel. While my real panel is original make by Nokia.. He again said if I pay captioned amount than he adjust this. He wants some money for this exchange.. In this circumstances i refused to him. Now I want your official person can check my old mobile any time any day.
