When i want to register to Umobile they said i have an amount with Yes4g ,then i just call the helpline 018-333000 and said when i want to subscribe to umobile they said i am listed in the system .I ask the operator what is the matter ,she said i have a clean record.What is the problem over here ,my record are clean but want to register with umobile they said I blacklisted by Yes4g ,call yes 4G ,they said i dont have name in their blacklisted list .Did you guys ever encounter this things ?
