Reliance Jio Infocomm — non delivery of jio phone

Address:	Ernakulam, Kerala, 683576
Website:	jio.com

I booked the jio phone on 25th aug of this year. Till now no clear idea or information abt when will it be delivered. When i tried to contact the customer care for jio phone segment, there is no option to talk with executive. Later i made a call to jio's general customer care number, i got the reply that they also dont know "whether it started its delivery or when wl it start". Since its almost 2 months from the advance payment, either i need refund or need nominal interest for the amt i paid for two months...
