Reliance Communications — data service

I have recharged my sim with 193 pack offering 1gb with 56days validity. Till 2gb it works good but after that it was loading on in 2g. If the sim is in 4g network the data does not load and it loads only when it is in 2g. It shows your 4g lite balance is 55235.11 and 4g data balance is 0. I have tried the customer care number 198 but there was no response and i cannot speak to customer care. I have even tried other tollfree number but the response was same. But neither of these. No one is there to attend your call. Please help me to get net in 4g
