Reliance Jio Infocomm — 4g data speed very low, calling not possible, sms cannot be sent.

I have jio 4g sim. When i have first purchased sim the data speed is good (With first recharge). When i recharged second time with 399/-, 4 g data, data speed is very low. Even during the 3rd recharge same problem persists. Adding to my woes. I can't call from this 4g sim. I can't send sms also. I feel cheated. I raised no. Of complaints to jio care. But they didn't
Solve my problems. They closed my complaints one sidedly saying i am not able to be contacted that too when i called from my other ph. No of different network. I feel cheated by jio. Please look into the matter.
