Reliance mobile operator is one of the service provider for users. The one of the drawback was its poor customer service. As one can’t contact in case of any need. They always show busy network. And sometime they deduct some money from your prepaid account. And when you ask about the deductions, they say that you have activated one of our service. It’s very difficult to negotiate with them. And when you switch out your sim for some time, then they switch off the sim permanently.
