Reliance Jio Infocomm — 10 add on voucher redeemed but not working

Recieved a voucher of 10 gb add on. Now I redeemed at myjio app and the same has been credited. But it is not working and data is not consuming from this pack after exhausted the base plan hence speed is capped at 128kbps (bits).
Tried many times but they are cheating in this case.
No help from customer care.
