Vodafone India — about company cug number

Sir, our company dgvcl's cug number [protected] has some technical problem. Earlier only cug number's incoming call were allowed. But since last 4-5 months, all customers can contact this number. This is 66 kv power sub station's number. So due to incoming calls of other than cug numbers, operator gets disturbed and we engineers cannot contact him in some emergency. So you are requested to stop other incoming calls other than cug numbers as soon as possible.
