Reliance Jio Infocomm — cancellation of jiophone offline booking and refund of rs. 500/-

Address:	New Delhi, Delhi, 110024
Website:	Reliance JIO

Till the time of writing this, no intimation of delivery of phone received. After giving a second thought, i decided not to buy this phone and approached reliance retail limited, reliance dx mini 15 a, sant nagar, east of kailash, new delhi -110065 (Store contact no. [protected]/143/217) to cancel my jio phone booked on 24.8.2017 by paying rs. 500/-. (Payment ref. No.[protected] dt.24.8.2017)

They refused to accede to my cancellation request saying they did not have any directions for cancellation of booking and making refund of rs. 500/-.
Will the concerned step into it and give required directions to the retailers/booking store not to deny the cancellation if some one so desires.
I do hope action will be taken and i, being an old man, shall not be put to any inconvenience. Booking done linking with my m [protected], new delhi - 110024
