I am getting calls and messages regarding a tata walky number [protected] a/c no[protected]. Whenever i got calls for verification or payment reminder i denied that i neither have applied for connection nor i know what person and company they were asking for.
Their sms and calls says rs 476 is pending since last 3 months and the number have been disconnected. I dont understand how can u activate their connection without sms verification. And every time your guys calls me and i tell him the case, they apologize and say we wont call u again. I have got almost 100 calls till now from different agents but no action have been taken yet. I want my contact number [protected] to be removed from that account as that connection doesnt belongs to me. You have their companies id and other details so go and grab them and stop irritating me and dont force me to file mental harasement case against you guys.
